COM port redirector
A COM Port Redirector (CPR) is application software that enables COM Port-
based applications to communicate over a network to remote equipment.
The main purpose is to enable the control of COM port-based equipment over
an IP-based network.
Com Port Redirector maps ‘virtual COM’ ports on a PC platform.
It redirects application data destined to an attached device via the PC’s local
serial (COM) port: Rather than going out the local port, the data is
transmitted across the IP-based wireless network using TCP/IP.
An ARF45-PRO attached to the wireless network receives the data and
transfers it from its own serial port to the attached equipment.
Conversely, data sent from the networked equipment to the serial port of an
ARF45-PRO is transmitted back to the application software on the PC via the
wireless IP-based network.
Com Port Redirector receives the data and presents it to the control
application as if it came from a COM port via a local serial connection.
