I only get unreliable/noisy transmissions if the plug is not properly inserted all the way to the end (which is likely since the plug housing diameter is typically a bit larger than what the phone case can take unless you remove the PCB from the phone, or have a very low-diameter plug housing of your cable. Initially I was using a 2.5mm to 3.5mm headphone adapter cable (the ones for attaching regular 3.5mm headphones to phones that have a 2.5mm plug, as those plugs are smaller than anything I've seen from the T191 serial cables so far). > + /* ignore modem status lines */ > + options.c_cflag |= CLOCAL; > + This is something I pondered of doing anyway... it simply made no difference on Linux / pl2303 so I never bothered... But I'm happy to merge it.
