I started with template.py, and use uv5r.py as a reference, since I have one of those as well. So far, I've mapped out the memory and established communication with the radio, but I'm having a problem when I read the data.  To establish communication, I first send a series of "?", followed by a "G". As soon as the radio receives the G, it starts sending data. What's happening in chirp, though, is when I do the serial.read(1), I'm getting the sent data back and then the radio data, as if the buffer doesn't clear. This uses an Icom OPC-478 style cable, where RX and TX are simply wire-OR'd together, so that does make sense. I should mention that this cable works fine with the OE software. Do I just need to look for the sent string in the response and filter it out, or is there a better way to handle this? I tried inserting serial.flush() after serial.write("G"), but when stepping through the program that seemed to do nothing.
