Identifying device name of a serial line?

» close window

The Question is:

 
On an Alpha 3000-400 there is an RS-232 synchronous/asynchronous port.  This
port should provide serial printer capability.
 
My question is: What is the driver called
for this port when invoking the SHOW DEV
command?
 
Thanks.

The Answer is :

 
  Depending on attributes ranging from the OpenVMS version to the alternate
  console settings to the particular system type -- the serial ports are
  typically either a TT or an OP device, usually either TTA1: or OPA0:.
 
  Far and away the easiest and most general approach to resolving this
  particular question is to simply plug a serial terminal into the serial
  line in question, log into the system, and look at the device name of
  the local terminal.
