3. the Tekram IR 660 device can in addition to attach a keyboard and mouse also print using IrTTP it can print using IrLPT but that is not so funny since it requires exclusive use of IrLMP and you don t wan t to stop the network mouse and keyboard just to print a document I ll try and see if I can get IrTTP printing working using a fifo as well Tekram has added a control channel in addition to the data channel so that you can get some status information about what is going on The name of their own protocol is P1248 It s published through the P1248 class and IrDA TinyTP LsapSel LM IAS entry so you can try to find it Canon is using the P1248 protocol and their printer monitor program BrintBuddy2 Japanese version is using this protocol now I don t know what they use for the data channel Maybe they support TinyTP directly in addition to the other methods You can try and look up the IrLPT class with the IrDA TinyTP LsapSel in the LM IAS and see if you can find it 3 16 Connection to Keyboard The Linux IrDA keyboard driver is now in user space Please see chapter Connection to Docking Station above Lichen Wang The so called IIDA D standard is designed to transfer Data It is not suitable for IR Keyboard IrDA D is what Dag ported to Linux OS and what MS ported to Windows OS The so called IIDA C Control is designed for Keyboard Joy stick etc I am not aware that there is any product in the market that

6. Note that there is another USB IrDA driver provided by the Linux USB Project for those devices called ir usb This module is NOT compatible with the IrDA stack and conflicts with irda usb Because it always loads first you have to remove ir usb completely If you are not familiar with routing issues I dare to recommend to shut down all external network interfaces with ifconfig during the first set up Then check with route n Also netfiltering iptables may cause problems so if you are not connected to a network you may disable it I have described the process in every detail to make every caveat as clear as possible The actual configuration is much shorter and easier During configuration I will choose to open three different terminal windows to watch the log messages from different programs 4 6 3 Plugging in the Dongle Now plug the dongle in and check the Kernel messages with dmesg hub c USB new device connect on busl1 1 assigned device number 2 usb c USB device 2 vend prod 0x50f 0x180 is not claimed by any active driver usb c registered new driver irda usb IRDA USB found at address 2 Vendor 50f Product 180 irda usb parse endpoints And our endpoints are in 02 out 01 64 int 03 irda usb init qos dongle says speed 0x13E size 0x20 window 0x2 bofs 0x4 turn 0x2 IrDA Registered device irdal USB IrDA support registered If you have already some other IrDA hardware configured on the PC the driver won t
7. Q13 If I try to make a connection say telnet it takes an incredibly long time for the login prompt to appear Answers by Renaud Baldura Dag Brattli and Hee Thong it s a DNS problem The resolver times out trying to reverse resolve the IP address of your incoming connection I think just renaming etc resolv conf to something else takes care of it or add some static bindings in etc hosts for the machines you want to access in your ad hoc network That should avoid the DNS lookups If both machines are in a private test environment put the following line in the etc host conf order hosts bind This will make the machine check the etc host file before doing a DNS lookup Remember to update the host file on both machines to reflect the IP and host names of the 2 machines Q14 Question by David LaPorte I was wondering if anyone has had any success getting the irda port on the Toshiba Tecra 740cdt working I ve read that it should show up at IRQ 11 ttyS2 Well I have a PCMCIA modem which steals ttyS2 and the PCMCIA controller steals IRQ 11 Does anyone have any suggestions Answer by Dag Brattli If you still have Win95 on your machine you should go to the device manager and change the PnP setup for the IrDA port something else than the stuff your re already using You could for example move away ttyS1 in Win95 so that it uses the values that the PCMCIA card is going to steal and then use the settings from ttyS1

14. Brattli Could you all check if the same thing is happening when your re using PPP and not using IrDA I guess the APM stuff shuts down the serial port so that the driver will need to reinitialize it when waking up again This is properly implemented by some of the PCMCIA drivers I know about but I really don t think the serial driver gets any events from the APM system So here you have your own little kernel project Start adding APM support to irport which will be the easiest thing and also to the FIR drivers then you can start adding a patch to the serial driver if needed AgainI think the PCMCIA subsystem may be a good source on how to fix it properly 5 9 Performance Testing netperf is a benchmark that can be used to measure the performance of many different types of networking including Unix Domain Sockets and TCP and UDP via BSD Sockets It provides tests for both unidirectional throughput and end to end latency Netperf page bing by Pierre Beyssac determines bandwidth on a point to point link by sending ICMP ECHO REQUEST packets and measuring their roundtrip times for different packet sizes on each end of the link 5 10 IrDA Protocols 5 10 1 IrDA Stack Figure 5 1 IrDA Stack Chapter 5 Advanced Topics 59 Linux Infrared HOWTO WDA 1 1 Protocol Stack PC LAN Adap Cell Phone PDA Printer PC PDA Digital Camera Product Application login Palm IIl ipd getty telnet pilot xfer pr fp wep
15. Chapter 9 Serial Infrared Remote Controller This is a simple cheap device that can be connected to any serial port to control most components that have infrared remote controls It was designed and built on a solderless breadboard and is finally designed as a PC board You may find this package here Chapter 9 Serial Infrared Remote Controller 67 Chapter 10 Infrared Tools for the COREL Netwinder PC Ryan Shillington wrote some tools to control the COREL Netwinder via infrared for example Server Side for the Corel Palm Administrator daemon It depends on having ir simple installed and up and running With this you can check and change IP addresses Gateway addresses setup eth1 etc You can also run simple commands AND you can check the Temperature Memory Load averages etc Client Side for the Corel Palm Administrator You can also run simple commands AND you can check the Temperature Memory Load averages etc A very basic infrared device driver This does not support IrDA only unreliable transfers It looks specifically for Remote Control signals and Keyboard etc It blocks and passes data up very differently You should get the tools at the Netwinder project Chapter 10 Infrared Tools for the COREL Netwinder PC 68 Chapter 11 ir ir is an interface program to Chris Dodge s RedRat 2 infrared controller to send and receive infrared signals to from consumer devices like TV s VCR s cable boxes and stereos It
16. FIR and dongle 3 1 1 Standard InfraRed SIR e Try to find out which serial port is used by the IR device You may do so by watching the output of dmesg If serial support is modularized do an modprobe serial first Look for an entry like Serial driver version 4 25 with no serial options enabled iETESASNOQ ar 008 Creo 4 as a 16550A first serial port dev ttyS0 itis S 01L aw 03000 ire 10 is a 16550A e g infrared port ttyS02 at 0x0300 irg 3 is a 16550A te g PCMCIA modem port If this is not the case you either don t have infrared support enabled in the BIOS or the SIR mode of your infrared device is not detected by the kernel Currently I know only two laptop models with this effect the HP OmniBook 800 and the Toshiba Libretto models I am not sure whether PnP support effects the detection of the IR port If you are unsure try it out and let me know the results Maybe you can use FIR mode if SIR doesn t work e n some situations you may have to use setserial dev ttyS 0 2 port OxNNNN irq M to set the values for your infrared serial port especially if the infrared port is a separate serial line You usually don t need to change the values For further information look into the FAQ section below If you don t use kerneld or kmod insert the irda module with modprobe irda Do Ismod It should show the modules irda and irtty now A look into var log messages should show the entry Serial connection established now

18. Infrared HOWTO 3 15 Connection to Docking Station Dag Brattli Connection to the Tekram IRDocking IR 660 This device is a docking station with LAN access printer mouse and keyboard You can also use them at the same time as the internal mouse and keyboard Just fire up gpm t ps2 dev irkbd and the laptop will make a keyboard mouse connection to the IR 660 Now I just have to make gpm read both dev psaux and dev irkbd and then make X11 read dev gpmdata and I should have the thing configured one problem gpm can handle multiple mice but Linux cannot handle multiple different keyboards So if you have one norwegian keyboard and one remote US keyboard like I have then things will be a little bit confusing I got a hint from Alan Cox about a project that is implementing real support for multiple keyboards so I ll check that out OK I sort of worked it out By using TIOCSTI on dev console you can insert scancodes directly into the tty queue This can be a problem for virtual consoles that expect to receive some translated and cooked keycodes but X happens to like raw scancodes so this will work quite nice when using X but not for other virtual consoles Anyway this is good enough for me so I will not use a lot of time converting the scancodes to keycodes and index them with some keymap just to make it work with text only virtual consoles As I see it the irkbd driver has now been successfully been ported to user space
19. IrDA devices in range Though it might be possible that the Linux IrDA service detects every new device automagically I only have good experience with the devices in range during the configuration process Keep your infrared devices together in a range below one meter and an angle of 30 degree There has to be a direct line of sight between them If this is not possible you may use a mirror an unused M CD should work quite good 2 4 3 etc modules conf Add the following lines to your etc modprobe conf for kernel 2 4 etc modules conf file attention the actual filename may depend on your Linux distribution IrDA over a normal serial port or a serial port compatible IrDA port SIR alias tey leiisge 1 1 3e EES IrCOMM for printing PPP Minicom etc alias Charan jor i6il seemim i y if you want IrCOMM support IRLA But currently the IrLAN protocol is no longer maintained by the Linux IrDA core team alias irlan0 irlan To be able to attach some serial dongles These values are hard coded in irattach not instance order alias irda dongle 0 tekram Tekram IrMate IR 210B alias irda dongle 1 esi ESI JetEye alias irda dongle 2 actisys AS SSI 0 alias irda dongle 3 actisys Actisys IR 220L alias irda dongle 4 girbil Greenwich GIrBIL alias irda dongle 5 litelink Parallax LiteLink ESI JetEye de He db db dk Chapter 2 Getting Started 15 Linux Infrared HOWTO alias ir

True Not only can you use SIR hardware to receive you can transmit too Of course there are some limitations Most IR remote controls use 38 KHz sub carrier 3 times 38 is 114 very close to 115 2 You can set the UART to operate at 115 2 Kbps 7 data bits no parity and 1 stop bit a total of 9 bits Each 3 cycles of the 38 KHz sub carrier can be received or transmitted as a byte of Ox5B Chapter 21 Infrared Remote Control IrDA 79 Linux Infrared HOWTO There are some physical limitations in addition to the fact that the sub carrier must be 38 KHz The SIR receiver is not as sensitive to 38 KHz as the IR remote receiver designed for that The SIR transmitter has a much lower duty cycle and thus can not emit a strong sub carrier either IR remote encodes the control signal by turning on and off the sub carrier at certain specific patterns Now that you can transmit and receive the sub carrier what remains is all in timing For transmit you have to know how many consecutive bytes of Ox5B to send for each burst of the sub carrier and how long to be quiet between the bursts For receive you have to know how many of the Ox5Bs you received are consecutive and how long the gaps were between these groups of consecutive bytes My experience with the IrDA link distance of SIR MIR and FIR is somewhat different from what Ryan said SIR MIR and FIR should all work from 0 to 100 cm but in practice a Some devic

148. tters designed for remote control The IR receiver for FIR and remote control are somewhat different A FIR receiver can receive remote control signals but can reach only 1 meter whereas receivers designed for remote control typically can reach 10 meters I have an ISA bus adapter with a National I O chip that supports both FIR and remote control I also have IR Dongles that include both FIR and remote control receivers Plus a transmitter for both modes I cannot find any software to support remote control functions I did my own experiments in DOS I cannot run Linux yet Anybody interest in this Chapter 21 Infrared Remote Control IrDA 80 Linux Infrared HOWTO Benny Amorsen wrote I have a laptop that is supposed to support ASKIR The mode of the infrared port can be switched to ASKIR in the BIOS Having to reboot to switch the mode in the BIOS makes it useless though so someone would have to find a way to switch on the fly Dag Brattli wrote It should be possible to use IrControl formerly IrBus for IrDA compliant remote controls I currently don t know about any remote controls using IrControl standard but there should be some out there anyone else who knows better You should go to the IrDA site and get the physical layer standard which includes IrControl I think Normal IrDA using IrLAP is _not_ well suited for remote control because of the connection oriented nature and just supports 9600bps for connectionles
