By counting the number of "x" messages I receive on the other end of the
Jabber connection.

this code will just continue to send "x" messages after an abort:
while( !$done ) {
$con->sendMessage("x"); # Send msg to Jabber server
sleep(1);
}
this code will send exactly 3 "x" messages after an abort:
while( !$done ) {
$con->sendMessage("x"); # Send msg to Jabber server
sleep(1);
print "foobar";
}
this code will send exactly 2 "x" messages after an abort:
while( !$done ) {
$con->sendMessage("x"); # Send msg to Jabber server
sleep(1);
print "foobar";
print "foobar"; # any additional number of print/echo commands will
do
}
I hope this helps.

Dennis
