Yes, you can do this. Here is an example for ping:
******************************************
local ckpingID = ""
local procName
on startPing ipaddr
if ckpingID is empty then
put "/sbin/ping"&&ipaddr into procName
open process procName for text read
put empty into field "field"
ckPing
end if
end startPing
on ckPing
read from process procName until empty
put the result into r
if r is empty or r is "eof" then
put it after field "field"
else
put " [" & r & "] " after field "field"
end if
send "ckPing" to me in .3 seconds
put the result into ckpingID
end ckPing
on stopPing
close process procName
wait .1 seconds
if procName is among the lines of openProcesses() then kill
process procName
cancel ckpingID
put empty into ckpingID
end stopPing
********************************************
To test that you will need a field "field" on the card. You can put
the above script in a card handler. Then put a couple buttons on the
card to call startPing and stopPing. Once you are happy with that,
then try with tcpdump.
Some years ago I found a number of bugs in "open process" on Windows,
so bad I don't use it there. There is a chance that some of those
are universal, so watch out and check for more errors than in the
above example.
Also, Rev has a fundamental problem with processes. It conceptually
opens up a bi-directional link instead of two one direction links.
This means you can't close the link to the process's stdin without
closing the link to its stdout/stderr. That means you don't see any
final word, and for processes that sort on input data, this is
worthless.
I hope that helps. Let us know how tcpdump with Rev works out.
