[Gambas-user] Re: Using serial component for plc comunications

[Daniel]

OK, there was an stupid bug in the SerialPort example I wrote:

...
WRITE #Sport,TxtSend.Text & Chr(13) & Chr(10)
...

Should be:

...
WRITE #Sport,TxtSend.Text & Chr(13) & Chr(10),Len(TxtSend.Text)+2
...

To tell the write function the real lenght of the data to send, so it
seems there's no bug in the serial port class but in the example.

Benoit, could you add this new version to examples?

Regards,

Daniel Campos
