The CRC algorithm used, is the same as in the XModem protocol. CRC for the last data packet is
only calculated for the actual data bytes in the packet. Pad last packet with 0x00 so that the data
section is 256 bytes long. The PacketID counter starts at 0.

Returns y0 60 09 ff if crc error -> retransmit
packet.

Reset ping ctr to 0.
pqrs = Pingval. Camera will respond with
OK if correct pingval received. Increase ctr
with 1 for next packet. Data section will be
dumped to stdout if it fails.
Send command to the command interpreter.
q=0: Debug mode off.
q=1: Debug mode on. Camera will send
stdout as visca messages in the following
format:
y0 50 [0-256 bytes stdout] 00 ff
Comments
Reboot the camera. This will also reset serial
speed to 9600.
p=0: Serial speed 9600. p=1: Serial speed
115200. Reply will be sent before the speed
switch takes place. Please wait 20ms after ok
before sending new commands.
