Fixed shell startup (?) 

At least on the alternative hardware, this "blindly sending" a reset command causes the shell to be terminated right away:
The driver acknowldges the reset command with a zero byte - and that byte ends up being read by DumpOutput causing it to branch to endOutput.

Maybe that sending a reset command is beneficial on the original hardware. Then another .if is required. Or DumpOutput shouldn't quit on reading a zero byte - the shell handler doesn't seem to send it on purpose(?)
