Command Control Menu (Port Selection Menu)

The Hayes Commands are a lower level of communication (then the menu system) between a modem

and device. These commands allow the RFI-9256 to emulate a landline telephone modem. Details of the

Hayes

commands are in section 7. The Port Selection Menu appears before the Hayes Command

Control Menu so the user can select the port to apply the changes to.

(D) DCD Control Menu

DCD (Data Carrier Detect) is used for flow control. The following menu in Figure 6-27 allows the

DCD signal

to be asserted by one of the following conditions. Each time a selection is made between (0)

and (8) that function becomes the DCD MODE.

This menu is not available if the Auxiliary port handshaking (flow control) is set to hardware.

Valid control conditions for DCD are ON (active) = + 12volts / OFF= - 12volts as per RS232 conventions.
