Anyone out there know how to do clever things with a Serial Parallel Converter (SPC) ?
We've got an old Sun workstation (SunOS 4.1.3_U1 2 sun4m) with an SPC. Connected through this is a dumb terminal (VT100) and a serial device (actually it's a tester for diagnosing faults with telecoms equipment).
Somehow, this lot is set up such that, when switching on the VT100 terminal, it gets connected directly to the tester so that it can issue commands to it & see the output.
However, if you hit the <break> key on the VT100, you then get the normal unix login prompt.
Unfortunately, the folk who set this up several years ago are long gone (leaving no documentation, of course) & we now need to duplicate this setup on a new(er) Solaris 2.6 machine.
I've checked out the getty stuff & it all seems pretty standard, with ttyy0c being the terminal & ttyy0d being the tester :-
[tt]
/etc/ttytab ttyy0c "/usr/etc/getty std.9600" vt100 on local secure
/etc/gettytab looks standard & std.9600 seems standard too.
# ls /dev/tty*
crw--w--w- 1 root 59, 12 Oct 3 09:27 ttyy0c
crw-rw-rw- 1 root 59, 13 Oct 3 07:30 ttyy0d
/usr/etc/stc/stc_defaults looks standard.
[/tt]
So, I'm hoping there's someone out there who knows how this is working ... TandA
One by one, the penguins steal my sanity.
