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 Window.
