SoftWindows performance can slowdown between 25% - 50% when the Express Modem software is enabled and waiting for a call. Either Fax Terminal or a data communication program set to auto answer can also cause this behavior.
If you do not need to use a modem while using SoftWindows, configure SoftWindows to ignore the modem port by going to the "Setup Menu," choosing "PC Serial Ports" and setting "COM1" and "COM2" to NONE. This should keep SoftWindows from accessing the serial ports which subsequently will turn on the Express Modem software. Also, be sure that fax receive is turned off in the Fax Terminal program.
In most circumstances, use Macintosh Modem software for better performance. The overhead of x86 emulation in SoftWindows and emulating a modem extract a heavy performance toll when using DOS communication programs.
