USAGE: update [-c comport]
filename
is displayed.
Meaning:
You are not specifying the correct number of parameters
for the update command.

An error occurred when the utility tried to transfer the file.
There could be a number of reason for this:
■
The null modem cable has become disconnected from the hub or
the PC during the file transfer. Reconnect the cable and start
again.
■
Power to the hub has been disrupted during the file transfer.
Check the power connection to the hub and start again.
■
An incorrect file has been specified and transferred to the hub.
Check the filenames and start again.
■
The utility must be run from MS-DOS. It cannot be used from an
MS-DOS Window within Microsoft Windows 3.1.
There are several very uncommon error messages. These are detailed
in the readme.txt file in the Agent\Update directory on the CD
accompanying the module.
