The cnc is dte as far as I know. And I am assuming since it worked without hardware handshaking on my pc, it shouldn require the same for the bbb either. That said, I have tried both the settings. With and without hardware handshaking. The only thing I can think of is for some reason perhaps, the default serial port settings must be different on the bbb (with debian) than my pc (where I previously successfully had communicated-windows) On 20 May 2016 08:19, "Wally Bkg" <[email protected]> wrote:
