Hi!

I'm looking for a way to "access" pins of a parallel port and/or a serial
port.
I want to be able to send something (a bit or a byte or ....) on a particual
pin and to read on a particular pin too.

By example, I want to send a signal (bit or byte) on the pin #1 and to read
other pins because the signal can get back on any pin (exept #1)

Anybody knows how to help me?  or when I can find any information?

Thanks a lot!

You're not going to be able to do this.  I know very little about parallel
comms but this just isn't possible with serial.  Visit VBxtras, and run a
search for PDQComm.  The examples all seem to work around modem connections
and emulation examples, however I've used the control to commuincation with
many portable devices.

If you need to look for a data stream on an unusual pin you are going to
have to modify cables to switch RX and TX to the pins requried.

Hope this helps.
Cheers,
Tull.
