I've made a mistake when i focused on the POS display, this has nothing to do with the POS display. The same error occurs if i try to send some data to a modem, or to a serial printer, or if i have nothing attached to the serial port. The problem resides somewhere else and i really need some help with this.

Thank you,

Joaquim
