18 Serial Socket Interface

The Serial Socket Interface enables defined communication between Com-

Servers and the device connnected to their serial port. Analogous to the

TCP/IP socket interface in Windows or UNIX systems, it provides the end

user with an external TCP/IP stack on the serial port while supporting up to

eight logical client and/or server sockets.
