DMPCMNTRC is new with V5R2. The old way is PRTCMNTRC. Makes a report of all the packets between selected IP addresses. I find the SST screens easier to work with than the raw commands - somehow, although they are controlling the same thing, one makes more sense to me. But SST is not usable in a program.

The report shows you the raw bytes in each packet, as well as parsing many of the fields in the packets. You can show the data in EBCDIC or ASCII, not both at the same time - run 2 reports, if needed.

Unless for verification, it might be enough to use the 400 trace, since it can give you both in and out. Again, unless you want to be sure that what the PC sent is what the 400 got, and vice versa.

Hi, Joe:

Not sure what you might have to use on the PC side, but on OS/400,
I think you might want to start by looking at the STRCMNTRC command
(Start Communications Trace)... ;-)  You can trace both directions, outgoing
and incoming...

Then you run for a while, then, ENDCMNTRC, then DMPCMNTRC to
"dump" the trace into a stream file in the IFS.  Not sure how to interpret
what is in there, though :-/

There are a bunch of freeware or shareware tools somewhere on the
net for use in Windoze-land... a quick google search reveals several at
this page: --
this one looks promising --

Have fun...
