Virtual COM Ports
Virtual COM ports, in Lizard Setup Software referred to as VCOM,
provide similar functionality as physical COM ports. In addition to
configuration, from a setup point of view there is no practical difference
between the two.
Instead of using a physical serial port, virtual COM ports tunnel the
traffic through a TCP socket connection, that is, it performs similar
functionality as the COM Server module.
Virtual COM ports can be configured to function as server (passive
connection), when remote computer initiates the connection to QML, or
as client (active connection), when QML makes the connection to the
remote computer. Typical uses for virtual COM ports are:
- Sending reports to a server socket on a remote server
- Accepting an incoming connection for service
- Connecting a sensor with a TCP/IP interface to the QML logger
Virtual COM ports are configured in the IP Services view as shown in
Figure 122 on page 267.
