i have a little something that can determine the PKT version but it won't tell
you if the PKT is valid or not... that's up to the human reading the values
from the screen output...

i have code i might be able to share with him for this but it is very
simplistic... basically, it reads the PKT header into a plain blank buffer...
then there are three PKT format headers that are ""overlaid"" on that buffer,
one at a time, and that's when we look for sane data in specific fields... it
is very simple TP code...

can you send me one of those PKTs that inspecta won't read? that's really weird
for it to not read them... make sure you archive it so that my system won't try
to process it as mail...

that'll be fine... he should be able to contact me via netmail or email...

hahaha!
