Crosspoint change commands do not immediately report changed status but instead the report comes up to a few seconds after the crosspoint change command is received 2 Automatic output change reporting is turned on and crosspoint change commands immediately report changed status as part of the response to the command Output change reports are automatic messages sent to the host whenever an output is crosspoint status i e connected source is changed For example the command U1 turns on automatic output change reporting When a crosspoint is changed the following message might be received X5 17 3 lt CR gt indicating that output 5 is now connected to input 17 on level 3 Alternatively if the router has only a single level or if all levels of the output are connected the same it might send Y5 17 I lt CR gt indicating that output 5 is now connected to input 17 Alternatively newer routers might use the V command instead of X commands to report a change V5 17 12 0 lt CR gt indicating that output 5 is now connected to input 17 on level 1 to input 12 on level 2 and does not exist or is not available on level 3 To turn off output change reporting use the command UO The difference between an argument value of 1 versus 2 has to do with the response generated by the router when it receives a crosspoint connect command V W X Y or Z command For example suppose

SPACE character appears before and after each individual command SPACES may also appear in character strings such as input output and level names Certain commands R Q L and G have character strings that appear as arguments The first three R Q and L have character strings only in commands sent from the router and these character strings are always terminated with a tilde character No special character marks the start of these strings they simply begin at the appropriate point within the command The G command on the other hand uses the tilde character to mark both the start and end of a character string argument Just before the router begins executing a command string it sends a leader to the host the same number as are required in commands from the host As it executes the commands some of them may generate additional output back to the host These command response characters are always preceded and followed by a space character making the response string easily human readable After the command string has been executed the routing switcher returns the string OK with a single space character before and after the word OK followed by the trailer anda CR carriage return ASCII OD character to the host This indicates that the command has executed successfully If an error occurs within any command of a command string the remainder of the command string is ignored and the rou

14. the router Some commands such as those that allow modification of router configuration settings might require entry of an administrator password before allowing the router configuration to be modified The K command is used to send the password but the router must be able to record that password in association with a particular remote user The router would save the password as the one established by the remote address specified in the M command The examples below show how this would work If the M command is not present in a control string received on a serial port the address assigned to the serial port itself is used as the address for all commands in that command string The M command works on an honor system There is nothing to keep a remote device from forging a false address This conforms with the philosophy of providing protection mechanisms that are not designed to be totally hack proof but rather are designed under the assumption that controlling devices will honor the system A dedicated hacker can always hack into the system if he chooses Note however that the server in a client server relationship can provide a great deal of added security for the system forcing the correct M command to be sent each time and filtering out bogus M commands received from clients When the router receives an M command in a command string it echoes the same M command in its response This allows th
