Hello Ocporbust,

this serial interface is configured for a form of tunneling called STUN

every SDLC frame that is received is placed inside a TCP segment and sent to

It should be related to some form of IBM or mainframe networking.

STUN SDLC is most commonly used in two environments: FEP to remote controller, and AS/400 to remote controller.


Hope to help
