Serial Port monitoring program

Im kinda stuck on a project because I need a program that can monitor both the Rx and Tx through a com port and save the data in chronological order. This is really important because I am trying to communicate to an important legacy hardware device with no company support (out of business). If I am successful, I can create a Open Source library for a important piece of research hardware.

Any help will be very useful, the program monitoring doesnt have to be free or open source but it will help 🙂

I came across that and this :

during my search, however, I donot know if either programs will capture both sent and received data in the right order. I am at home so I cannot try them out but if someone has used either or can try them on a serial device and give me an answer, I would appreciate it. I wish I could try it right now but I am not going to be able to until atleast monday.

Thanks for your reply TechnoPro.
 
Just out of curiousity, what is this, some university electronic engineering project or something? I am not an engineer, but I did learn some parallel port programming for fun
 
Getty? Never heard of it, sorry, I am really new to programming with serial ports. I wish I had gone into computer science as a major.
 
PortMon from Sysinternals is what you want, but you have to keep it mind that it monitors all information flowing between the applications and the port. That is, if there are no apps to read the data coming in over the serial port, you won't be able to see that it made it to the PC unless of course you have PortMon running on the other side which it pretty much sounds like you can't do. Normally this is an acceptable limitation but you have to keep it in mind. See TechnoPro's post for the link. Sysinternals totally rocks at these utilities. I use PortMon as well as a few other of their utitlities on a regular basis.

If that app doesn't work for you, it sounds like you might need a (hardware) protocol analyzer of some sort to sit in between the two endpoints. These are generally a PITA and pretty hard to track down. Somebody might have one at your work/school.
