Overview
Test Terminal (WCom2)
The Test Terminal program enables you to open a port, send characters and
commands to the port, and toggle the control signals. This application can be used
to troubleshoot communications on a port-by-port basis.
Using Test Terminal and a loop-back plug on a port will help test serial ports and
verify port operation by allowing you to send data out the port on the transmit
side, loop the data back to the receive side and view the received data on the
screen.
If you have a peripheral device connected to the serial port and know the device's
command set, you can also send commands to the device. For example, if you have
a modem connected to the port, you can use AT commands to query the modem
and dial out to the host system.
Port Monitor (PMon2)
The Port Monitoring program offers a summary of all Comtrol device statistics in
one view. It also enables you to verify operation of all Comtrol device ports from a
single window. The statistics are displayed in a familiar spreadsheet model: each
COM port is a horizontal row, and each vertical column displays a variable or
value for the respective COM port, for simplified port monitoring and superior
ease of use.
Port Monitor can also produce statistics and reports that can help you verify COM
port operation and the connected peripherals. Some immediate feedback includes:
• The state of the modem control and status signals
• Open ports
• Raw byte input and output counts obtained from the device driver
• Port errors
The available statistics include:
• Instantaneous characters per second (CPS) calculations
• Minute, hour, and day CPS averages and peaks
• Carrier detect (CD) signal runtime and transition count
• Reports can be automatically generated on an hourly and/or daily basis, and
can cover all ports collectively or a separate report for each port. You can also
set how often the values are recalculated, fine-tuning thoroughness against
system efficiency, and automatically run external batch files to perform
additional processing and analysis.
