TTYredirector Knowledge Base

I am seeing problems with data transferring. How do I troubleshoot this?

1.  If using a fax application, make sure that the application is set to send a class 2 or 2.0 fax.  Class 1 faxes are too time sensitive to be redirected successfully.

2.  Ensure that the flow control settings for the application and device server match.  Note:  Hardware flow control can only be used if the device server supports the COM Port Control protocol (RFC-2217).

3.  If the serial or modem server doesn't support the COM Port Control protocol, make sure that the baud rate, stop bits, data bits and parity settings that in the application match those on the server, and are also the values that the endpoint device is expecting.

4.  Capture a Trace Log using the TTYredirector trtrace utility while at the same time capturing the TCP/IP packets with the Ethereal utility.  Ethereal for various Linux distributions can be downloaded from:  http://www.ethereal.com/download.html#otherplat

5.  Open a support case with Tactical Software on this page: Support Request Form

Be sure to include:  

- The logs that were captured in Step #4.

- The application and device server that are being used.

- Any errors messages or logs from any of the programs or devices that are handling the data transfer.
