Serial Port tool

[badcompany]

Looking for a 'free' tool so I can check com port is communicating correctly on pc. Its a serial port via usb converter and I am having trouble getting the device connected to it (scales) to work.

Any ideas?

Simple protocol analyzer eg http://www.232analyzer.com/232default.htm

Plenty on google, although most are not free (but have free trials so may suit for a one off).

They should allow you to run your application as normal but still see the data. Alternatively you could just open the serial port with PUTTY but unless your commands are text based you won't be able to send them to the scales.

portmon from Sysinternal

start it before the app that uses the port , its pretty easy to use
