7.1 DIMM-PC/MD
For controlling the modem select a suitable COM Port address and IRQ.
The Modem appears at the ISA Bus (DIMM-IO Bus) as device with UART 16550
compliant register set according the specified settings.
The modem will be controlled by AT (Hayes) commands. The baud rate is selectable
from 300...230.400 baud asynchronous. 10 and 11 bit transmission is supported
(including START and STOP bit).
For modem control just use a standard terminal program (TELIX, Procom etc.).
For instance, hyper terminal or similar can be used for Windows based PCs.
The baud rate will automatically set by typing „AT CRLF“. Then the modem will answer
„OK“
The AT command reference is based on the original CONEXANT documentation. The
complete document can be downloaded from our webpage, section “Embedded Internet”.
Since the modem acts as standard serial device, no specific software and operating
system drivers are required. Usually, the modem is directly supported by the operating
system (as “modem with standard hayes command set”).
