Each port must map to exactly one other port on a different multiple-
xer. Error messages will be given for three or more occurrences of
the same letter, or if two ports on the same multiplexer are mapped
together, or
if
a port is mapped to nowhere. (For explanations of the
error messages refer to APPENDIX B).

Control-C aborts the command.

Control-Z terminates input, keeps the new mapping and returns the

2.7 SETTING UP THE PORT CHARACTERISTICS
The terminal characteristics are set up at the MUXserver 100 by means of its
supervisor port, or from the remote user terminal using the DEFINE PORT
command. When configured, the MUXserver 100 downloads this information to
the remote DECmux II unit and the relevant port.
When you set up the port characteristics, you set up the characteristics for the
asynchronous port and not the terminal itself.
You can list the current port characteristics using the SHOW PORT command.
This command shows the characteristics which are stored in both the perma-
nent and operational databases.
