File transfer appears slower than it should

 If you have a Universal Asynchronous Receiver/Transmitter (UART) that is

compromising data throughputs, we recommend you replace it with a special I/O card.

 If you are running under Windows 3.1 and have a 16550AFN UART, you must replace

the Windows serial driver, COMM.DRV, to take full advantage of the UARTs speed.

 Check the serial port baud rate in your communications software and make sure it is set

as high as your UART allows.

Data is being lost

 Your UART may not be reliable at serial port speeds over 9600 bps or 19,200 bps.

Reset your serial port speed to a lower rate or replace your serial port with a faster one.

 Check the serial port baud rate in your communications software, and make sure it is set

as high as your UART allows.

 Make sure the flow control method you selected in software matches the method

selected in the TA.

There are

characters on the monitor

 Your computer and the remote computer may be set to different parities. Check with the

remote system with which you are communicating and set your communications

software to use the same parity as the remote system.
