[PD] comport issue

[renaud.herne at belgacom.be]

Hey,

I got something similar last night.
I tried to interface a serial mouse to one of my com ports.
The idea behind this is to get more handy controls at no cost.
I checked the proto of the mouse I found back in stuff with a terminal and a hex editor.
It mached the description of a Microsoft 2 button mouse (3 data words of 7 bits 1200 bps no parity one stop no handshake)
So far so good
But I didn't recieved anything in comport (after turning off the teminal to release the com)
I also tried something less exotic (another PC connected wit a null modem cable to the port  - Both running 9600-8-N-1 no handshake)
But I wasn't able to get anything.
I noticed that open 0 opens COM1,  open 1 opens com 2...

The number box at the bottom of the commport example should disply something right?

I am running 0.38.4-extended-RC8 under Windows XP

Any hints?

Thank you

Renaud

Hmm, your problem to me sounded just like mismatched baud rates.  
Can't think of anything else at the moment.

If you are not part of the solution, you are part of the problem.
