I'm confused by this statement, if you're using tip(1) then the file 
/etc/remote tells tip what the serial port names are to use and they can be 
dialout[abcd] if you want.

>/dev/ttys shows that /dev/ttyc would be the non-console serial line.  i'm

It sounds like ttys are configured correctly. You need to find out what the 
maj/min numbers are for the on board serial ports on PMAX and make sure 
that the device entries exist. TO do that I suggest that you connect the 
port you're interested in to a PC or something that you know works (a 
terminal is even better if you have it available) and then just use 'cat 
/etc/motd > /dev/ttyxx' where ttyxx is the device name. That will verify 
that you've got the correct device nodes established.

Then edit /etc/remote, create a new line for your tip line by copying one 
of the hardwired lines, and then change the device to be the one you need 
to use.

Now try 'tip <yourname>' and it should say 'Connected' if it does then 
typing will appear on your test terminal/PC and typing on that machine will 
show up on your screen. (Real terminals with a loud bell are great because 
you can test them by sending them ^G and hearing them beep without having 
to see their screen)

As I recall on the VAX port I needed to make new device nodes to get this 
to work.
