UART - Universal Asynchronous Receiver Transmitter
(External Modems Only)
If you are running Windows 3.x or you have upgraded your system from
Windows 3.x to Windows 95, you can run MSD to determine your
UART setting. In DOS, type MSD at the Windows directory prompt and
then press ENTER. Follow the on-screen instructions to access the
COM port settings panel. In this panel you should find the UART chip
used. Match the UART type listed in MSD with the serial rate listed in
the chart below. Select this serial rate (sometimes called the “port rate”)
in any communications software you use.
If this is your UART... Select this serial rate
16550 115.2 or 57.6 Kbps
16450 38.4 Kbps
8250 19.2 Kbps
NOTE: DO NOT select a 28,800, 14,400, or 12,000 bps
serial port rate if offered. Your modem will NOT work correctly
with any of these settings. Fix or lock the serial port (baud) rate.
If it’s referred to as autobaud, select OFF.
