Your guess is correct. It is inherent to DOS!

The serial port looks for acknowledge of sent data, when it doesn't
get it because the printer buffer is full; it times out, and stops
trying. The mode command has a switch to work around the problem.
I was thinking it was /P for printer, but I typed MODE /? and got:

Configures system devices.
Serial port:  MODE COMm[:] [BAUD=b] [PARITY=p] [DATA=d] [STOP=s] [RETRY=r]

So, I suppose my memory failed me. It is r for retry.


... Keep an open mind and let it all hang out.
