Hi.
Its been sometime since i played with QB under WFW but you could try this.
Assuming that you have 2 comm ports (mouse in 1st)
and whatever your trying to talk to on the 2nd.
From WFW control panel try giving the port assignment a false address.
1st port is probably 03f8 int 4
2nd port is probably 03e8 int 3
changing the 2nd to say 02e8 int 7 (provided nothing else lives there, maybe printer interupt)
This should fool WFW enough to allow a DOS prog to work.
As i say, its been a while since i experimented with it but it should hackle. Let us know how it goes..
