External Modem Control

Description
The system supports an external modem (see Note 1) plugged into the RS-232C port. Serial
interface/remote programming software, which supports 9600 BPS, enables remote system
maintenance by accessing the external modem. A pre-assigned AT Command (see Note 2) can
be sent to an external modem automatically when it is plugged into the RS-232C port. The
extension user is also allowed to control the external modem by sending the pre-assigned AT
Command.

a)
