Is it possible to monitor the serial port?

[ZhangZQ]

I want to monitor the data send and receive in the comm port, is it possible
to do this?


Thank you very much!

Due to the nature of how most serial applications take over the com port,
you'd probably need to write a replacement serial driver to accomplish this.

it first.

There is a free tool called TALBreakout avbailable at the following
URL that should do what you require quite nicely.

Download the TALBreakout program and read the help file to see how it
works. Basically it is designe to run in a PC with two serial ports
where you connect the PC in between another PC and a device - i.e.
like a breakout box. It then displays everything that goes through the
serial line in both directions.
