By default, Avanti presents two serial ports under OpenVMS, OPA0 and TTA0.  Procedures that check for serial devices by scanning for a TX device will need to be updated to reflect the ports presented by Avanti.

Example of obtaining the terminal device name:

$ TERM = F$GETDVI("SYS$INPUT","DEVNAM")
$ SH SYM TERM
 T = "_TTA0:"

Note:TX serial devices can be added using the Digiboard serial card.  See 5-Port Serial Card Support (OPenVMS).
