Modem Control Effect

When modem control is enabled for a port, the PortMaster interprets the carrier detect (DCD) signal as follows according to the type of ports:

Login

If carrier is not asserted, the port is unavailable. If carrier is asserted, the PortMaster initiates authentication and displays a login prompt.

Device

If carrier is not asserted, the port is unavailable. If carrier is asserted, the port is available for the device service.

Twoway

If carrier is not asserted, the port is available for device services. If carrier is asserted, the port attempts to establish a network connection and disable the device service.

Network Hardwired

If carrier is not asserted, the port is unavailable. If carrier is asserted, the port attempts to establish a network connection.

Network Dialin

If carrier is not asserted, the port is unavailable. If carrier is asserted, the PortMaster initiates authentication and displays a login prompt.

Network Dialout

The assertion of carrier has no effect, but the transition of carrier from asserted to not asserted causes the port to be reset.

Network Twoway

If carrier is not asserted, the port is available for network dialin. If carrier is asserted, the port attempts to establish a network connection and disable the network dialin.
