Hi All, Is is possible to map to terminal server ports ? I would like a user program to fopen /dev/vs2 (or some such) and have this 'virtual' device behave like a real serial port (eg. /dev/cua1). When the terminal server boots it can open a permanent telnet session to the bsd box on port xxxx. Does bsd have anything that maps the incoming session on port xxxx into a device that users can open ? If for argument sake the terminal server telnets to port 2001 for it's line 1, and 2002 for line 2, then /dev/vs1 must always map to 2001 and /dev/vs2 must map to 2002 etc etc This is somewhat different to the normal ISP situation where dialins on the terminal server might auto telnet to port 23 on the bsd box and are given a login session on the next available /dev/ttypx. My outgoing connections must be certain about which device maps to what terminal server line !!! DEC used to do this sort of thing very well under Ultrix or VMS with a protocol called LAT. I'm hoping for a simple unix world solution. Regards, Greg Laslett. greg@abseil.com.au
