COM1 woes

[Guest Uncle Marvo]

Hi folks

 

Sorry if I'm in the wrong group here, but I Googled for a problem I had with

COM1 and found the answer from a MoeGreen after much headbanging, it proved

to be the right answer.

 

But here is something which I think is impossible ...

 

I have two devices which send data to a PC. Both 9600,N,8,1, both work on

one PC. On the other PC, only one of them works. I could understand if both

or neither did, but how can it be that one works and one doesn't?

 

XP Pro SP 2, laptop, Clevo motherboard, Intel P4, COM1 is a standard port

with the FIFOs switched off.

 

TIA
