Answer 1

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.

thax i connected scope to my pc to check the transmited data and i get strange bit string ..

[Walter Roberson]

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.
