On the back of VaxStation II's, there is what appears to be a console port. Can anyone tell me what the major and minor device #'s would be to access this port (for Ultrix)??

You are correct; it is the "console" device. You can either do a "mknod /dev/ttycp c 38 0" or "cd /dev ; MAKEDEV ttycp" to create it. It can be used for logins, printers, etc. _____________________________________ Brian V. Smith (bvsmith@lbl.gov) Lawrence Berkeley Laboratory I don't speak for LBL, these non-opinions are all mine.

It seems that the ttycp driver of Ultrix 3.1 can't generate 7bit/even output. In 8bit/noparity mode it can't handle XON/XOFF flow control. It worked in Ultrix 2.2. ~~~ Matthias Kandler Inst. f.

So, when up as a workstation, then /dev/console is assigned to the session manager window (if you use it) or dumps elsewhere major/minor 0/0 - I use this port for some stuff (modem work etc)... to use this port when running as a workstation, here is an ls -l crw-rw-rw- 1 root 38, 0 Dec 11 11:12 /dev/ttycp You can do (as root): # cd /dev # MAKEDEV ttycp and the correct device will be made... please note you need to set the baud rate with the dial selector in the rear of the unit - 2400bps works fine - You also need a 9pin to 25pin cable to utilize 'normal' rs232 devices... another gotcha, is that this port is character interrupt driven - steady stream of data either way keeps my GPX at loads over 2 (at 2400baud)!!! have fun... -jj -- Jeff Janock @ Digital <jeff@imokay.enet.dec.com> +1 508 486 6102
