1.3 VxComm Technology

In general, writing a TCP/IP program is more difficult than writing a COM Port program. Another
issue is that perhaps the existing the COM Port communication system was built many years ago
and is now outdated.
As a result, a new technology, VxComm was developed to virtualize the COM Ports of the PDS-8x1
controller to allow up to 256 COM Ports to be used on a 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.
