I'm trying to emulate an existing program which writes to the Serial port.
Using Portmon, I can see that the existing application does the following:
So i worked out how to send all those messages to the serial port.
My application (according to portmon) does the following:
All looks good right? The same?
Hmm, thats what I thought, but my application does NOT do the same as the existing application.
Im missing something here - Its either something differemnt between the log files or Portmon is lying.
Does anyone have experience in this (PLEASE), cos its driving me barmy
Thanks

Hmm, thats what I thought, but my application does NOT do the same as the existing application.
Im missing something here - Its either something differemnt between the log files or Portmon is lying.
Does anyone have experience in this (PLEASE), cos its driving me barmy
