4. Serial Interface

4.a. TTL and RS-232 Serial
4.b. Baud Rates
4.c. Command Protocols

You can use the serial interface for three general purposes: querying the qik for information, setting its configuration parameters, and sending it motor commands. Motor commands are strictly one-way; the qik responds to all other commands by transmitting a single byte that either represents information that has been requested or feedback on the effect of the issued command.
