Commands Example Response Control
- - ? ? product name\
SW rev n.m\
FW rev r.s\
protocol ver 4.0\ Hello command.
Note 1: No other commands will be
available until the card has received
this hello.
Note 2: This command will also
enable checksums.
Note 3: Cards are designed to be
hot-swappable. To sync with the start
of a new command, the cards will
wait for a <lf> character before
looking for a valid command.
