I have a question for a VAX Hacker, not a bug report. I hope this is
the correct email address; if it's not, could you forward it? Thanks.
My advisor has one of Athena's new Vaxstation 3100s in his office. We
want to attach a printer to one of the serial ports. Now, I think I
can mess around with the Athena software enough to set the baud rate,
start up a printer queue and assign it a name and all of that; my
problem is that I don't know what special files in the /dev directory
are attached to the two serial ports.
I don't have any good documentation for the 3100, but based on some
manuals I saw for a Vaxstation 3500, it appears that the required
driver is "ss", and that the serial port devices should be /dev/tty02
and /dev/tty03. The boot sequence for the 3100 shows that indeed the
ss driver is in the kernel and loads at boottime, but when I try to use
those files (e.g. "cat some_junk > /dev/tty02") the error "No such
device" is generated. The same thing happens for all the /dev/tty0* files.
The /dev directory has files tty00...tty07, and their major,minor
device numbers are 1,0 ... 1,7. Can you tell me:
1) What are the correct special files for the serial ports on the 3100? (I
want to use direct connect, not dialup.)
2) If they are /dev/tty02 and /dev/tty03, is the problem that the wrong device
numbers are assigned? If so, can you tell me the correct device
numbers?
Thanks for any help you can give!
