... port and set parameters for serial communication. [Parameters] intCom : serial communication port number; dwBaudRate : baud rate; byParity : parity; byDataBit : data bits; byStopBit : stop bits; byFlowControl : fl ow control; lpdwSysError : system error returned. thanks

Otto, I don't see where I can set the post speed, parity etc...

Am I missing something?

... In fact, I don't understand the most samples concerning serial communication! Even in the help functions I can't find for example to set an EVEN parity? I hoped to get some input to take the first step to improve that FWPPC can communicate with our vending machine…. DEFINE COMM <oComm> ...

HOLA A TODOS... ESTOY TRATANDO EN IMPRIMIR EN UN IMPRESORA EPSON LX-300, DE PUERTO COM, PERO NO HE PODIDO.... SOLO ME PASARON ESTE FRAGMENTO DE CODIGO EN CLIPPER Y NO SE COMO ENVIAR DATOS A ESTE PUERTO Y PARA ESTO UTILIZO IOLIB..... ESPERO Y ME PUEDAN AYUDAR.... :oops: :lol: Y GRACIAS POR SU AYUDA.....

alguien me podria ayudar a hacer la llamada desde fwh

Muchas gracias por la ayuda

Antonio,

It's possible in FWPPC initiate comm port eg. baud=9600, parity=e, data=8, stop=1 before send data to port ?

Thanks
Pawel

... (ie. baud rate, stop bits) and how? EMG Enrico Tested on HP IPAQ 6515 I tested port 1 opened OK without any change. No need to set baud, parity...etc If i set 2 or any other value, it will not open correct. If you need any further test, let me know Richard
