Connection is made by entering a port number or port name.
Disconnection is accomplished by entering a disconnect code string or by lowering an RS-232 control lead on the accessed port. The DCB Universal Switch can be used to connect modems, terminals, PCs, RS-232 control ports, etc. The Universal Switch allows both local terminal and remote dial-in access. All ports can be active at the same time. The user always gets positive feedback, there is no blind switching.
