[comp.sys.apple2] Making the Null-Modem Connection

rmichel@pro-grouch.cts.com (Russel Michel) (07/05/90)

Help!  I've been trying without sucess to establish a null-modem
connection between my '286 machine and my IIgs, in hopes of exchanging
several megs of data between the two systems.  The cable connection is as
follows:  modem cable from the GS modem port to a null-modem adapter to a
gender-cganger to the clone's serial port.  All components have been used
sucessfully in other applications, except for the null-modem.  I checked
that with an ohmmeter; all the proper lines are crossed.  I've tried
various baud rates (keeping both serial ports at the same speed); I've
tried every combination of flow control I can think of; I've tried
different settings for data & stop bits, parity, DCD & DSR/DTR
handshaking, etc.  For software, I've been attempting to use ProComm Plus
on the clone, and ProTERM or MouseTalk on my IIgs.  The closest I've come
to establishing a working connection was random characters filling the
screen on the GS.  Can anyone with experience in doing this feat shed any
light on my problem?  Thanks in advance for any replies.
