MINI-MODEM (33.6 KBPS DATA/FAX MODEM)
modem’s maximum transmission speed or faster;
however, not all serial ports can handle speeds
that high. Set the serial-port baud rate to 115,200
bps if your computer has a high-speed serial port
with a 16550AFN UART or equivalent and
Windows 95 or 98; set it to 57,600 bps if it has
Windows 3.1x. If you have an older computer with
a 14550 UART, set it to 19,200 bps. Older
Macintosh computers can use a serial-port baud
rate of 57,600 bps, and newer ones, 115,200 bps.
To see what UART is in your serial port if you have
Windows 3.1x, select File, Run in Program
Manager, type MSD, and press RETURN. Select
COM Ports to see the UART type. If you have
Windows 95 or 98, select Start, Settings, Control
Panel, and double-click on the Modems icon. In
the Modems Properties dialog box, click the
Diagnostics tab, click the port the modem is
connected to, and click More Info to see the
UART type. Note: Both programs may identify a
14550 UART as an 8250A UART. If you have an
80386 or later computer, your UART is most likely
a 14550 or 16550AFN.
7. If the software has an autobaud selection, make
sure it is disabled. Autobaud applies only to older
modems, and can cause problems if enabled.
