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

I would recommend a async protocol analyzer to see the full picture.  You
should be able to pickup some of these at a surplus store relatively cheap.
See this link and search for the Navtel Datatest 2
http://www.torontosurplus.com/test/telecom.htm
there are also a few other vendor solutions which require proprietary
hardware (i.e. 16 nit ISA/EISA cards) which provide the interface hardware
for a in-series connection to the data path being analyzed.

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.
