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. Port switching requires no cryptic code entry. Ports can be named and accessed by that name or by port number. If the device being accessed can lower an RS-232 control lead on command, as DCB products can, the hardware disconnect method can be used. Data transparency insures that no control codes will inadvertently cause a disconnect.
