Windows-95 Serial Port Communications Problem.
When communicating with the CAT-1000B, if you experience difficulties during memory
file transfers, a hardware flow problem may exist. Computers running under the
Windows-95 operating system default the UART (Universal Asynchronous Receiver
Transmitter) transmitter buffer to sixteen character bytes. The UART will not stop
transmitting until its buffer is empty. This causes a hardware overflow condition.
To resolve this problem, the UART buffer needs to be reduced to one character byte to
match the CAT-1000B.
