Usage:

mme     gerout
vfd     6/TYPE,12/0,o6/06,h12/TERMID
tra     NOTCONN_RTN

Where:

TYPE: is a two-digit octal number indicating the type of the terminal. This should be initialized to zero; it will be filled in by MME GEROUT.
TERMID: is the terminal ID name of the terminal whose type you want to determine.
NOTCONN_RTN: is a routine that should be called if the terminal is not connected. If the terminal is connected and the type can be determined successfully, MME GEROUT will return to the instruction following the TRA instruction.

Description:

This version of MME GEROUT determines the type of a particular terminal. As a side effect, it can also be used to determine whether or not a terminal is still connected.

MME GEROUT will fill in the TYPE field with one of the following octal values.
