There's a tool either in the GP-2 directory on your HD or on the CD that
configures GP-2 to use port-4.
I had the same problem, but I reconfigured my Modem to use port-2. Doom etc.
don't have a utility to use port 3 or 4...

I'll be back for Christmas."
"It's sharper than a page of Oscar Wilde whitticisms rolled into a
point,
sprinkled with lemon juice and stuck into someone's eye."
