- I have a 386 box that's been running ISC UNIX 2.2 (SVR3) for nearly two
- years now. It has a Digiboard Digichannel PC/16i (16-port serial board)
- that has an unusual problem every now and then.
-
- Every now and then (two or three times since the box was first configured)
- accessing one of the ports either directly or through a dial-up results in
- the following message during a login.
-
- Warning no access to tty (not a typewriter)
- Thus no job control in this shell
-
- I found that the "not a typewriter" message is coming from /bin/login and
- the rest of the warning message is generated by tcsh (/bin/csh will
- generate a similar message). I have never been able to figure out what this
- warning message means or what to do about it short of rebooting the system.
-
- A few more clues: (1) "ps -ef" will not show an attached tty for processes
- run from a session connected to the "misbehaving" port. (2) /etc/whodo
- has the same problem (no tty reported attached to a process on that port).
- (3) tty *does* report the correct /dev/ttyxx port when logged into the
- misbehaving port. (4) 'su' will not run if logged into the bad port.
-
- Any advice, hints, etc. would be appreciated...todd
