15. COMMUNICATE WITH OUR COMPUTERS Lately the UCC Microcomputer HELP line has received an inordi nately large number of calls on the same subject how can get my micro to communicate with the BERS The answer is that you need some hardware and some software Here are the details The hardware Communicating with UCC s CYBER or VAX computers usually means com municating over phone lines To connect your computer to the phone system you will need a MO DEM Modems are devices that translate the signals used by your microcomputer into audio tones which can be sent over phone lines Modems used over voice grade phone lines operate at either 1200 baud or 300 baud If you plan on buying a 1200 baud mo dem be certain the modem uses the Bell 212 protocol The protocol the modem uses for translating your microcomputer s signals into audio tones is important because there are two incompatible protocols for use at 1200 baud We use the Bell 212 protocol If you buy a 1200 baud modem that uses the Bell 202 protocol it won t work with our computers Not surprisingly you have to connect the modem to your micro computer This means you need a cable to make the connection Not all cables are created equal The cable you use to connect your printer to your micro may not work with your modem It is a very good idea to get the cable for the modem from the same place you buy the modem and to specify with which microcomputer the mo
16. N parity There are other settings for communications param eters that work but seven data bits one stop bit and even parity seems to be the choice available on nearly all communications pack ages You must also specify your modem s baud rate 1200 or 300 baud The ucc Micro group maintains a communications package called COM that is optimized to talk to our mainframes CYBER and VAX Because COM is designed to com municate with the CYBER and the VAX you need not specify any communications parameters except baud rate You can also use COM to transfer disk files from your mi crocomputer to and from our main frames Many of the general purpose communications programs can also be used to transfer disk files to and our mainframe computers But since a general purpose program does not know what kind of com March 1984 puter it is talking to you must give the program some hints about how to send or receive a file When you send a file to the CYBERs the first step is to put the CYBER into record everything I send you mode You do this by typing the TEXT command On the vAX the equiva lent command is CREATE Once the host computer is recording you tell the micro to list out the serial port the file you are sending After the file has been sent you tell the host computer to stop recording by typing a control c for the CYBER or a control z for the Capturing information from the mainframe w
