How old is LSPPP.EXE? It must be very antiquated if it doesn't allow a
baud rate > 19600. I remember Ashton-Tate Framework III 1.1 allowed a
baud rate up to 19200 (or was it 38400?), and ports could be COM1, COM2 or
COM3, but not COM4, but that software dates to 1989. I think there still is
a Framework with a Web site http://www.framework.com
no longer associated with Ashton-Tate or Borland.
2400 bps was a normal modem speed in 1990, and they were going up to 9600.
14.4 K modems were still a few years away.
