5.16 MAP (Part of the Communications Sub-
directory)
This command is privileged and is executed in the communications sub-
directory (that is, in response to the COM> prompt).
It
is used to modify the
logical asynchronous link connections between the DECmux II units and the
MUXserver 100. The default settings have each asynchronous port on the
DECmux II units mapped in a logical connection to the MUXserver 100 and
the LAN. Alternative connections are possible, for example, with logical asyn-
chronous links established between ports on the DECmux II units. The MAP
command is used to establish these logical links (see Chapter 2, Section
2.6).
Use the MAP HELP command for assistance.
The output from this command is designed for an ANSI video terminal.
Enter MAP to produce a display showing blocks of information for each mul-
tiplexer known in the Network.

The MUXserver 100 (or a remote DECmux II unit, if the
connect command is in effect).
Where X is the letter A or B, and n is a number 1, 2, or
3. This gives the port to which the MUXserver 100 is
connected and its distance from the Self Mux; for exam-
ple, A2 is connected to the A port and is the second Mux
on that port.
The MUXserver 100 must
be
MASTER and hence, con-
trol the MAP configuration. (See the SYSTEM Command
for details of Master and Slave.)
