where ipaddress is the IP address of the Serial Device Server and portnumber is the Serial Device Server TCP port number. For example:

telnet 192.168.5.53 9100

In this example, if you have a serial printer or other device capable of displaying ASCII characters connected to the Serial Device Server serial port, then every character you type should be printed on that serial device (buffered serial devices may need you to type a control character such as a formfeed (CONTROL-L) before the characters are printed).

RFC 2217 Remote Modem Control Support

RFC 2217 allows you to access your device’s modem control signals over the network. It is especially useful for migrating applications that use modem controls from a direct serial connection to a serial device server network connection. You can utilize RFC 2217 from the Silex Serial Port Emulator software (see below), or by connecting to TCP port 9200 from your application program.

ECable Mode

Normally, it is up the computer to initiate a connection to the Serial Device Server. For some applications, it is desirable for the Serial Device Server to initiate the connection to the computer. The Serial Device Server supports this capability through its ECable feature.

To set ECable mode, use a web browser to access the Serial Device Server internal web pages (see chapter 3 for instructions on using the internal web pages). After you have logged in, click I/O port on the left side of the screen.

You can now enable ECable mode and set the required parameters.

1.Enable ECable mode by clicking the radio button.

2.Enter the address (Destination Address) of the computer or other device that will be communicating with the Serial Device Server)

3.Enter the TCP port number (Destination Port) used by the destination device for communicating with the Serial Device Server (must be greater 1023).

4.If desired, change the ECable Connection Attempt Time. This specifies the time interval between connection attempts. For example, by default the Serial Device Server will try once every 30 seconds to make a connection to the destination device; if it fails to make this connection, it will wait 30 seconds before attempting again. Changing this interval will reduce or increase the amount of network traffic.

5.It is also possible to use UDP instead of TCP for communicating to and from the Serial Device Server. If you wish to use UDP, then:
