Calls for connecting to the carrier system

The openUTM client may use UPIC or OpenCPIC as the carrier system. An XATMI application program must therefore explicitly sign on to the carrier system using tpinit and sign off using tpterm, i.e. the program has the following structure:

Basic structure of a XATMI-Programm

tpinit()

XATMI-Aufrufe, z.B. tpalloc(), tpcall(), tpconnect(), ...tpdiscon()

tpterm()

The two calls tpinit() and tpterm() are described below.
