Question:

Does anyone know how to make sSendString send the character with the ASCII code of zero?

If you do this:

   sSendString(socket,strcat(num2char(65),num2char(0),num2char(65)))

it only sends 65 and 65 (omitting the zero). It was driving me crazy so I finally got a packet sniffer to check it, and it is indeed omitting the zero character.

(You need to send a zero character when negotiating the binary mode transfer in a telnet session.)

Answer:

You cannot do it with the string functions.

Need somethng like a pPutByte(port,0) to do it. pPutByte is in the Serial Extender.
