ya u canmake the serial null modem cable by using 2 serial mouse
but the problem is that there r 5 wires in the serial mouse
like White, Green ,Orange, Blue ,Brown
and up till now i had studied that u need 6 wires for that
u can do it by a little trick
connect dtr(4)---->dtr(6),dsr(1) u can pel of a little copper wire and put it in the whole no#dtr(6),dsr(1)then they will be interconnected to dtr(4) by using 1 wire:)
isnt it tricky
thanks i am also working on it
any how i will do it today
by bye tc wish u good luck and health
aoa
