You can send data out a virtual com port and verify communication all the way through the setup to the physical serial port. To perform this test, connect the device server to the PC's physical serial port. The communications path makes a big loop like this:
PC Using Virtual Redirector Com Port --> Network --> Device Server --> Device Server Serial Port --> RS232 Serial Cable --> PC's Physical Serial Port.
To test RS232 connections:
Select All Com Ports (or a group of com ports to which the desired com ports belong ) and click the General Tests tab.
Click the RS232 tab.
Note: Only real com ports and RFC2217-enabled virtual ports support steps 3 and 5.
If desired, change the serial port settings.

Baud Rate |
Speed or baud rate to use for the serial connection. Valid baud rates are 300, 600, 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600, 115200, 230400, 460800, and 921600. |
|
Data |
Indicates the number of character bits. The default is 8 bits. |
|
Parity |
Select parity type. The default is None. |
|
Stop |
The stop bit follows the data and parity bits in serial communication. It indicates the end of transmission. The default is 1 bit. |
|
Flow Control |
Flow control manages data flow between devices in a network to ensure it is processed efficiently. Too much data arriving before a device is prepared to manage it causes lost or re-transmitted data. The default is None. |
In each Com Port section of the window, select a com port from the drop-down list and click the Open button.
For each com port, in the RS232 group, click the RTS and DTR buttons to toggle the standard control settings between High (0) and Low (1). Verify that the connection is working properly.
Note: Rx Data is the number of bytes received on the com port. Rx EOF is the number of EOF messages received on the com port.
To send text to the other com port:
a. Type text in the text box. As you type, the TX Data field indicates that data is being sent. If a com port receives text, the text displays in the text box for that com port.
b. To clear text, click the Clear Text button.
To send data to the other com port:
a. Click the Send Data button.
b. In response to the "Run Data" message, click OK. The data transfers, the Tx Data field shows the number of bytes transferred so far, and the white progress bar beside the Tx Data field for the receiving port shows the progress of the transfer.
c. To stop data transmission, click the Stop Send button, or if a "Run Complete" message displays, click OK.
