UART (External Modems)
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.
Select this
If this is your UART... serial rate
16550* 115.2 or
57.6 kbps
16450 38.4 kbps
8250 19.2 kbps
*All U.S. Robotics internal modems have a 16550
UART.
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).
