For security reasons the Multiplexer must be directly connected to a terminal
to access the MAINTENANCE MENU.

Login to the unit as CMGR at the initial prompt.  All access passwords will
apply as usual.  On login a $$ prompt will appear.  Type UPGRADE MENU
<return>. The prompt ARE YOU SURE? will appear.  Type YES  <return>
and the MAINTENANCE MENU will appear.

A new version of the Router firmware may be downloaded to flash memory
via the console port using Kermit.

If a suitable communications program is resident on the PC it may be used.  If
there is no such program available the upgrade disk includes a shareware
version of ProComm.

Connect the PC via COM1 or COM2 to the SUPERVISOR port of the
Multiplexer. This port is configured DCE and therefore a straight cable (no
crossover) is required (see Echo LANlink User manual.)  The
communications package should be configured to 9.6Kbps, 8 bits, 1 stop bit
and no parity.

Start the PC communications program, or ProComm from the upgrade disc.
ProComm will default to COM1.  Should the Multiplexer be connected to
COM2 press ALT P and select 22 for COM2.

If ProComm is being used press the <PgUp> key on the PC, then enter 2 for
Kermit.

Enter the Upgrade File Name e.g. A:\>LANLINK1.1.

ProComm will display the file size and how many bytes have been
transferred.  The download should take approximately 15 minutes.
