Message-ID: <773@massey.ac.nz> Date: 14 Jun 90 05:39:01 GMT Organization: Massey University, Palmerston North, New Zealand Lines: 29 X-Reader: NETNEWS/PC Version 2.1 I very much appreciated the discussion posted by in response to my earlier posting. I have since received a copy of acucntrl from Pyramid Australia and a program called uutty from comp.sources. I haven't tried the acucntrl stuff but have played with the uutty code all day. It seems to solve the problem of the modem and the login process jabbering away at each other but doesn't fix the tty contention problem. The tty has crw-rw-rw as its rights but when tip tries to access the line it gets /dev/ttyi20: resource busy all ports in use it gets the same message when run as root. I must be missing something really simple. I had thought that Unix was supposed to treat devices and files the same, if the permissions allow shared access then shared access is possible, the onus being on the programs to ensure that they do sensible things. This would appear to be correct for files but not for ttys. -- ----------------------------------------------------------------------- Glen Eustace, Software Manager, Computer Centre, Massey University, Palmerston North, New Zealand.
