When I use the serial monitor and send the 'Z' (Button [A]) command, it doesn't work. Neither does sending the 'L' command (it moves down but doesn't select).
I've added a call to `doLoader()` into the `setup()` function and that starts the loader, but then sending the program doesn't work – the bar flashes showing that data is received but the code doesn't run (including blinky).
`sendFile.py` has a similar result. The Gigatron is reset, the loader starts, code is sent, but it doesn't run.
I'm using the most recent code from github and a V4 ROM.
I've tried both a Nano and a Mega 2560 (using the Uno configuration) and both have do the same thing.
Another issue is that the controller passthrough doesn't work (using the Nano). Push any button has no effect on the Gigatron.
I'm thinking that the bit stream is getting out of sync but I don't know how to test this (I don't have a signal analyser).
Any help would be appreciated.

UPDATE
Pluggy McPlugface works fine (even with my shoddy wiring). All the keystrokes are passed through fine and Ctl-F2 loads BASIC.
