When connecting a cellular modem to any device via the RS-232 serial port, consider the baud rate required by the device that is being attached. For example, when connecting a cellular modem to either a CR200(X) using a 18663 or to a CR10(X) using a SC932A, the RS-232 baud rate of the cellular modem should be fixed at 9600. For these devices, 9600 baud is the default baud rate.
