'[EE] Serial monitor'
2005\04\25@134717 by Gerhard Fiedler

While browsing semi-randomly :) I found this tool. It's a serial monitor
that monitors what a program (any program) on your computer does with the
serial port. While working on serial comm protocols, I often wished I had
something like that. It's less frequent these days, but I still thought
that someone might find this interesting.

Without this tool, the only other ways are to route the serial data through
a dedicated serial analyzer or through two COM ports on a PC (one in, one
out) and a program that connects the two and displays the traffic. Both
methods are quite a bit clumsier than this program.

I haven't tested it, and it's not free (starting at $50). Requires a WinNT
type system.

You forgot the link and/or program name. ;-)

Very interesting BTW.

   Is it the one from http://www.hhdsoftware.com ?

   I bought it quite a while ago and it is great...

Best regards,

Yes... Here's the link I forgot :)

HHD Software, Serial Monitor
http://www.hhdsoftware.com/sermon.html


While getting the link from my storage, I also found this one. It does it
differently: by using two COM ports. Advantage is that it can observe the
traffic even if none of the devices is a PC and that it's cheaper,
disadvantage is that there's more hardware involved and that it's merely
external.

I always use www.sysinternals.com/ntw2k/freeware/portmon.shtml
which does both serial and parallel ports and is free

It does not have a protocol analiser but pretty good filtering

You can use one com port on the PC with a T junction made with 3 x D9's, a
resistor and a diode. The PC will display the two way traffic. no diagnostics

It's somewhere at this site;

Neat :)  

Even though they are correct in that most so-called full-duplex protocols
actually work half-duplex, this probably won't work well with most
half-duplex protocols that use software handshake like XON/XOFF.
