Uniwell POS Dx915 Serial port communication

[Cerebro]

Hi,


Anybody here who have done serial port communication to a POS machine specifically Uniwell Dx915 in C++?

I'm having trouble with the command format. I can't get the machine to respond to me.

If so, please add me candy_bitongga at yahoo.com. I'd like to ask some questions.

Or we could keep the conversation here.

Thank you.
