RTFM OpenVMS V7.1 Release Notes Chapter 6  Device Support on OpenVMS
Systems Section 6.5

6.5  Naming Serial Line Devices on Alpha Systems
----------------------------------------------------------------------

V7.1

OpenVMS has changed the way it handles the second serial port on the
following Alpha systems:

     o  AlphaStation 200, 400, 500 and 600 families

     o  AlphaServer 1000, 2000, 2100, and 4100 families

If one of these systems is booted with the console environment
variable set to graphics, the name of the serial line (COM1) will be
different from that in previous releases. The COM1 device is called
TTB0 instead of OPA1. In this case, the COM1 device is controlled by
SYS$YSDRIVER instead of SYS$OPDRIVER.

If the console is set to serial, the COM1 device is called OPA0.
