serial() to associate the port with an identifier. set() to configure things like speed. fopen() to open the port. fprintf() or fwrite() to send the data.

Strange how so? For example what do you get if you fwrite(s,char(0)) ?
Note that the start and stop bits have their logic levels reversed compared to data bits, and note that a data bit representing 1 is sent as a negative voltage with a 0 represented by a positive voltage. Also note that RS232 sends the least significant bit first.
