My codes whit VB it works well directly whit my COM1 (whit serial cable), when i connect whit bluethoot i change the port to COM40 (My laptop recognize this port and works well whit Sequencer), somebody help me, i work whit VB6 and does not work, my velocity is 115.2K, all works well whit Hiperterminal and Sequencer, but not my VB6 o MATLAB, but whit cable if possible 
VB6 is old and probably will not recognize serial ports above 4. I don’t know what to tell ya.
