LAN/WAN and Intranet/Internet Applications
Virtual COM-UDP™ works on any Ethernet, Wireless LAN (802.11x), or TCP/IP network, and can
send serial/UDP data packets to any IP located inside or outside the network.
Here is how Virtual COM-UDPTM might fit into your network scenario:
Scenario 1:
“Software Tunneling”
2 PC’s need legacy serial based software linked from one to the other over an IP network.
Creating a “TCP socket” between them seems to create issues that are hard to manage.
UDP is a better solution, but the software cannot be re-written. Virtual COM-UDP™ is a great fit.
Scenario 2:
“Remote Serial Device Connection”
A PC’s legacy serial based software normally receives data device on a local serial COM port
from an externally connected device such as a bar-code reader, or handheld GPS. The
software resides on a machine that cannot be moved, yet the serial data instrument (BC
Reader, GPS handheld, etc) needs to be relocated to a remote or wireless environment.
The device and software have their own communication s protocol, and do not need a full-
blown TCP connection in order to communicate. A simple protocol such as UDP is desired.
With a serial data modem setup for UDP packet data mode, you can now send data to the
host PC software, enabling the virtual connection of the device and software. Perfect solution.
PC with legacy serial
communications software and

will receive
‘inbound’ serial (barcode) data
from the device connected to a
remote wireless modem.
