We are trying to use tip(1C) on a VAX 750 4.2BSD system to communicate with another 4.2 UNIX system (on a Callan) over an RS232 line attached to a tty port. I made an entry in /etc/remote that looks like hao-ig:dv=/dev/ttyh8:br#9600 Then the getty for that port was disabled (by putting 0tttyh8 as it's line in /etc/ttys and doing kill -1 1, standard port-disable procedure). When we then try "tip hao-ig" the response is "all ports busy". I tried fooling around with various things in el, ie and oe fields as well, but the response from tip is invariant. What have I done wrong and/or left out? Has anyone else used tip(1C) for this sort of thing? --Greg -- {ucbvax!hplabs | decvax!noao | mcvax!seismo | ihnp4!seismo} !hao!woods CSNET: woods@ncar.csnet ARPA: woods%ncar@CSNET-RELAY.ARPA "If the game is lost, we're all the same; No one left to place or take the blame"

Thanks to all who responded to my tip(1C) question. At least 10 people told me that tip prints "all ports busy" when it cannot open the /dev/tty port in question. A misleading diagnostic at best, but it is cured by chown'ing the /dev/tty port to uucp. --Greg -- {ucbvax!hplabs | decvax!noao | mcvax!seismo | ihnp4!seismo} !hao!woods CSNET: woods@ncar.csnet ARPA: woods%ncar@CSNET-RELAY.ARPA "If the game is lost, we're all the same; No one left to place or take the blame"

Also check for lock files in /usr/spool/uucp (just rm a file like LCK.ttyh8, as long as you know it's invalid.) [in the original message ttyh8 was used, any tty of course.] -Barry Shein, Boston University

I suppose, there is a lockfile in the directory /usr/spool/uucp, named LCK..ttyxy. This is used to prevent tip from using a line, when uucp is active on this same line.
