Surely a hardware splitter has to be the easiest way?
(otherwise you'll get COM port conflicts or the OS will at
 least perform sensible stream mgmt)

Subject: is any one sniffing comports on win2k or XP?


I have an application that I need to steal data from. This application 
is initalizing a bar code reader and I would like to see the escape 
sequences that are used to initialize this particular device. There are 
bajillions of DOS apps that claim to spy on a com port but I have had no

luck with them. Every app I try to use results in a com port in use 
error when I fire up the app I want to sniff. Does anyone have any 
applications to try? I need one that will allow me to monitor a comport 
passively in win2k or XP and it must at the same time allow another 
application to query or connect to the com port. I need to be able to 
see the data being passed back and forth between the application and the

device.
