Hi, Revisiting old business: I had mentioned ages ago that it could be handy for certain purposes to run pppd or sliplogin on a pty. Under 1.something, it was not possible, but somebody suggested that it should be possible with a few minor changes in the pty code. I honestly don't know if this was ever done. Specific scenario: I am on a secure corporate network, well connected. I have my trusty 386sx/16 terminal server. I have another 386sx/16 with a friend's hard disk, and have loaded 2.0R onto it. I'd _like_ to connect the new box via PPP to my friend's old box, which would be helpful while configuring and putzing around, but his old box is a 24/7 system, and the one available modem is running a PPP link to the Internet. This suggests that I have a data path: 386sx/16 --> terminal server --> telnet to friend's old box via Inet --> pppd If only pppd would talk to a pty. I lost the original message(s) about this that I sent some time ago - or at least cannot find them. Could some kind TTY hacker please comment? (looking through the tty code reveals a few things: the manpage for 4 tty is out of date and refers you to <sys/termios.h> for a discussion of TTYDISC/TABLDISC/SLIPDISC, by the way - wrong.) I suspect it has something to do with the code in tty.c dealing with TIOCSETD, but I don't have any familiarity with the tty code... Thanks, ... JG
