Apple and IBM Communications Problem

[Marilyn Smith <squig@delphi.com>]

     Hi there.
     I want to convert some stuff from my Apple IIGS to my IBM.
However, I am having a communications problem.  I am intending to
use the Apple IIGS's built-in modem port.  I have an eight pin male
cable going to a twenty-five pin male plug at the other end.  Since
my IBM has a male port, I must use a gender changer.  Now, what is
happening is this.  On one IBM computer, I get something that
vaguely resembles what the GS is sending.  On another IBM, I get
absolutely nothing.  I would think that I might need to use a null
modem adaptor, but I already tried that.  Same result.  I am using
software that depends entirely on the control panel settings.  Any
help would be appreciated.
            Configuration Information is as follows.
IIGS Rom version $3, System ID $0
Modem port Control Panel settings are as follows.
