- I am currently connecting a number of systems in our computer room via
- serial cables to a Xyplex terminal server. Connections to individual ports
- on this server are made using the 'xyp_ptyd' daemon supplied by Xyplex,
- running on a central console 'host' system. This daemon essentially makes
- a connection between each port on the serial side of the terminal server and
- a pseudo-tty on the UNIX host system. I can then connect to these individual
- pseudo-ttys using the 'console' package from Ohio State, but that's irrelevant
- to this problem...
-
- The problem is that I need to be able to generate a break signal on one of
- the serial lines on the terminal server. I have no problem in modifying the
- Xyplex xyp_ptyd code in order to do so, but I don't know what/how to send
- to the terminal server (over the network connection) to tell it that I want
- it to generate a break over the serial line.
-
- Can anyone help? Is there a 'normal' way of passing this kind of thing through
- TCP/IP? The Xyplex manual seems to indicate that it will do the same thing
- in the opposite direction - i.e. a break on one of the serial lines can be
- propogated through the terminal server and over TCP/IP to a host system... how?
-
- Thanks...
