USB Serial RS232 Sniffer

Need to sniff a RS232 connection.

http://www.232analyzer.com  $69.96
The free one does not sniff.  Can use it as a terminal and watch the detail but as a sniffer - no.
The single user license is $69.95 and apparantly that canenable the sniffing function but given the lack of other people programs to actually meet their promises in that regard, I hesitate to hand over $70 just to try it because I am doubtful that it would work or that I would get my money back.

Bizarre $160 for a couple of D9's and a bit of wire.  Sounds like rip off.

Useful information regarding wiring up sniffer cables.

Portmon (Microsoft?) Free

The help states: "Simply execute the Portmon program file (Portmon.exe) and Portmon will immediately start capturing port output."  But it always states :"disconnected" in the title bar and the help does not mention XP.  Seems to have been developed for 98. Never seems to log anything.  Gave up

SniffUSB2.0 Freeware

Ran it.  Does not work.  Web page says need dot net 2.0.
A check of C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 looks like dot net 2.0 to me.
Unplug USB adapter and wait then re plug it.
High light it and click filtercontrol>install
Somewhere along the lines it started to log but the file seems to record all sorts of calls to whatever.  I think more detail than what I am looking for and I can not find the data that I am typing in hyperterminal.
Gave up

The log is full of junk and no sign of what I type out on hyperterminal.

Look amazing.  See the word "Hello" at the right.
So Had to close hyperterminal.
Run Free serial port monitor.
