1.3 VxComm Technology
In general, writing a TCP/IP program is more difficult than a COM port program, or the COM port
communication system was built many years ago.
As a result, a new technology, VxComm was developed to virtualize the COM ports of the PDS-
220Fx Series to allow up to 256 COM Ports to be used on the central computer. The VxComm
driver saves time when accessing serial devices through the Ethernet without the need for
reprogramming the COM port software on the PC.
The VxComm driver controls all the details of the Ethernet TCP/IP programming technique,
meaning that, with the assistance of PDS-220Fx and VxComm technology, your COM Port program
will be able to access your serial devices through the Ethernet in the same way as through a COM
Port.
