6.4.5 Serial server/client mode option

This mode requires CELL200 series operating system 2.00 or newer. Find the CELL200 series OS
version in the OS Date field of the Status Tab. For more information, see Updating the operating
system and firmware (p. 80).
In serial server/client mode the module connects to the cellular network and opens a listening
port. When a client connects to the listening port, the CELL200 series will be in "serial server"
mode. In serial server mode, all data on the active port (RS-232 or CS I/O) will be routed through
the listening port. When no client is connected to the listening port, the CELL200 series will be in
"serial client" mode and all data on the active port will be sent and received through the initiated
TCP client socket connection.
