X.25 over TCP/IP through Remote Procedure Calls (RPC)

A different approach is to access a front-end X.25 device such as the PXS or a PC using LayGO X.25 hardware and software. In this case only LayGO API calls are redirected through the TCP/IP connection. A read or write RPC client function will pass the user data to a read or write RPC server function which accesses the LayGO protocol stack at the PXS.

The PXS can be accessed from any of the LayGO client applications.
