Kenneth,
Please can you confirm how your datastream is presented?
I'm pretty sure that RS232 is async only, but I may be wrong, did you get
this from the type of connector?
http://www.lammertbies.nl/comm/info/RS-232_specs.html
if you have got a syncronous serial line, what encapsulation is used - or is
it proprietory?
If you can find a way of conveting your datastreamn into UDP, then you can
use the unicast UDP multicast forwarding feature to get a single udp packet
over your frame relay network.........
STUN relies on TCP I think so this isn't scalable.
MAybe there are some cisco blue people who may be able to help you further
good luck
Adam
