How TTYredirector Works

TTYredirector command line utilities and daemon

  • trconfig configures TTYredirector devices with settings including the IP address (or hostname) of a device server and the TCP port number for a device on that server.
  • trquery shows TTYredirector device settings.
  • trtrace shows TTYredirector activity in real-time for diagnostic purposes.
  • The ttyredirectord daemon converts the serial data stream of the application to a TCP/IP connection to the device server.

TTYredirector devices at run-time

  1. When an application opens a TTYredirector device, the daemon establishes a TCP/IP connection to the device server using the corresponding IP address (or hostname) and TCP port number.
  2. If the device server supports the COM Port Control protocol, the daemon automatically negotiates it and can perform additional detailed configuration of the remote device.
  3. If the server requires a login to use a port, the daemon can automatically provide a user name and password.
  4. As the application reads and writes the TTYredirector device, the daemon relays the data stream to the device server.
