There is no way that you are going to get to use your modem ......
It sounds pretty bad......
I think that You neeed some nogada!
Grab a screw driver and unscrew your modem out and try to set a irq's as
follows :
if com1 then
irq=4
else if com2 then
irq=3
else if com3 then
irq=4
else
irq=3
but..here is a better solution/../...
if
extra law of Paul
com1 and com3 can't be used simultaneously....
com2 and com4 can't be used simultaneously....
if you want to use iyagi...
so put mouse on com1 and modem on com2....or figure it out yourself!
bye.......
