    DTR signal (often used to disconnect a call), and flow control. Once the serial port is set, the Ether232Plus forwards the data to the serial device unchanged. If any changes to the Com Port or modem line occur, the Ether232Plus will automatically send a notification packet to the host.
  • Page 29 Connection Control key. If the parameter is set to DTR/DSR Con- trol, the Ether232Plus tries to open a telnet session as soon as DSR is detected from the terminal, but the timeout function of most hosts makes this option somewhat unreliable.
  • Page 30 Typical configuration for most applications. Use tcp(tunnel) mode when the Ether232Plus must be able to initiate TCP connections and accept TCP connections from the host. In this configuration, the Ether232Plus can communicate with the TCP/IP host as if it were virtually connected.

  • Page 31: Port Setting

    This makes for slightly faster data flow. Setting the Remote IP address to all zeros puts UDP into "reply mode" and the Ether232Plus will send data to the last address it received data from. For peer-to-peer communication, the host address must match the Remote IP defined in configuration.
  • Page 32 When the remote end is ready to receive data, it asserts the CTS signal to tell the Ether232Plus to start transferring data. If the remote end is unable to accept the data as fast as it is received from the Ether232Plus, the remote end negates CTS, and the Ether232Plus suspends data transfer.

  • Page 33: Port Mode

    13-bit transfers. 4.3 Port Mode Port Mode specifies the type of serial connection the Precidia unit has with the serial device. You can choose from RS-232, RS-422, or RS-485, according to the type of connector on the attached serial device. To ensure you are using the correct cable for your serial device see Appendix E: Pinouts and Power Supply.
