[lwip-users] Re: [lwip] SLIP support in Windows

[Conny Öhult]

Hi Fabio,
I assumed in my previous answer that you where using lwIP's sioslipif.c .
If you are using uIP and the C64 port I would add it to rs232dev_poll at 
the end of the default fallthrough (before the break).

The code could be implemented like this (haven't tested it):

/* Modem command 'AT...<CR>'. Send OK in response to modem cmd */
  static u8_t ok_str[] = "OK\r\n";
  if(slip_buf[0] =='A' && slip_buf[len] == '\r') {
         for(j=0;j<sizeof(ok_str);j++) {
                 SIO_SEND(ok_str[j]);
         }
  }

  In case of a DCC you would add something like the
  following:

  /* Send CLIENTSERVER in response to CLIENT (for WinNT direct cable 
connection) */
  static u8_t server_str[] = "CLIENTSERVER";
  else if(len+1 == 6 && slip_buf[0] ==
  'C' && slip_buf[5] == 'T') {
         for(j=0;j<sizeof(server_str);j++){
                 SIO_SEND(server_str[j]);
         }

}
