Bob:    Under Toggles from the Select Device To Edit Menu, do you have
an X beside CTS/RTS indicating Set ON.  If this is set on, QmPro uses
hardware handshaking between the modem and your computer.  If this is
not ON, this will cause a modem buffer overflow resulting in an aborted
transfer.   This is required for high speed modems.

        Without the above set on, your computer is sending data faster
than the modem can accept it, causing the buffer overflow.  It says that
in a rather confusing way in the QmPro Manual....  Page 43 and 298 in my
manual... (10/01/92 Printing)
