OnCell G3111/G3151/G3211/G3251 Series User’s Manual Introduction
1-2
Overview
OnCell G3111/G3151/G3211/G3251 gateways can be used to connect any serial device to a cellular
network and support a number of different operation modes. The OnCell COM driver turns the
OnCell G3111/G3151/G3211/G3251’s serial ports into virtual COM ports that allow you to
communicate with your serial device remotely over the cellular network. The OnCell
G3111/G3151/G3211/G3251 comes pre-installed with the TCP/IP protocol suite to transmit data
back and forth between the serial device and GSM/GPRS network.
For some applications, serial data must be delivered reliably even if communication is disrupted.
The OnCell G3111/G3151/G3211/G3251 provides a function to ensure that serial data is buffered
in case of a communication failure. When a communication failure occurs, the serial data is
buffered in the OnCell G3111/G3151/G3211/G3251 until communication is resumed, at which
point the buffered data is sent to its destination.
