Hello All,

I see, thanks a lot guys for your help, but I'd like to solve my last
doubt that is about the output of serial cable that come of
SPECTRACOM(2). My doubt if is possible to have 2 hardwares using the
same channel or serial cable? On the output of this cable there is one
adapter that convert the serial port db9 to 2 x db25. I tried to use
before the 2 hardwares using these 2 x db25, but I havent successfull.
Is it possible? I dont know if explain right, but anyway I can explain
again in another way.

Thanks a lot,

Marcos Luiz Onisto
