A system and method for dedicating an externally configurable modem under system software control at a local peer for communication with one, single, predetermined remote peer, thereby providing the equivalent of a dedicate line by operating a single modem at the local node. The modem to be dedicated to the predetermined, single remote node is initialized to answer mode and reconfigured to originate mode when needed. The process of configuring the modem of the local node establishes a point-to-point protocol (PPP) route for establishing a physical connection path to the remote node.

System and method for establishing virtual and physical connection paths between peer systems

A control system for the carriage drive of a line printer includes a microprocessor which controls a carriage drive stepper motor through programmable timers and interface adapter along with other non-print units of a printer mechanism. A control counter in the carriage drive responsive to feedback pulses from the stepper motor coacts with the timers to control various operation of the stepper motor during line feeding of a print medium and is used by the microprocessor for preventing loss of control of the carriage drive due to interrupts from other devices.
