Why Vxcomm Technology - ICP DAS USA PDS-220F Series User Manual

1.2. Why VxComm Technology?

In general, writing code for a TCP/IP program is more difficult than for a COM port
program, or perhaps 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 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 fiber optic
network without the need for reprogramming the COM port software on the PC.
