Terminal: Serial port

The Question is:

what does openvms know the two serial ports on an
alphaserver 1000/266 as - is the address tta0 or
something like that ?  we are wanting to use these ports
to connect serial printers

The Answer is:

    	Until V7.1 OpenVMS knows the two built in serial ports as TTA0, and
    OPA1.  Unless you have booted with an alternate console in which case
    they are OPA0, and TTA0.  As of V7.1 they will be TTA0, and TTB0 unless
    you use an alternate console.  In that case they will be OPA0, and
The easiest way to determine the device name of any particular serial port
is to plug a terminal into it and log in.  SHOW TERMINAL will tell you the
device name.

Serial ports are typically called TTAx, OPAx, or TXAx.
