Changing default telnet port number

[frank]

Hi,

Is there any way I can change the default telnet port (23) to a different port number ?.

Search for fnStartTelnet in the utasker project, in the uTasker demo this is in debug.c in the function fnConfigureTelnetServer

The first parameter to fnStartTelnet is the port number.

        Telnet_socket = fnStartTelnet(temp_pars->temp_parameters.usTelnetPort, (2*60), 0, 0, fnTELNETListener);   // 2 minute inactivity timeout

You can see that the port is pulled from the parameters.

Looking at the Parameter definition in application.c you can see

const PARS cParameters = {
    PARAMETER_BLOCK_VERSION,                                             // version number for parameter validity control
    (unsigned short)(2*60),                                              // default telnet_timeout - 2 minutes
    (CHAR_8 + NO_PARITY + ONE_STOP + USE_XON_OFF + CHAR_MODE),           // {43} serial interface settings
    23,                                                                  // TELNET port number

So the port number is defined here, just change this to which ever port you want, I've just changed it to 223 on my test setup and it worked as expected.

Cheers
