Software upload commands
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.

*
8x ae ff
Reset ping ctr to 0.
CAM_Ping

pqrs = Pingval. Camera responds with OK if cor-
rect pingval is received. Increase ctr with 1 for
next packet. Data section is dumped to stdout if
it fails.
CAM_Stdin
*
8x a4 [0-256 bytes
stdin] 00 ff
Send command to the command interpreter.
CAM_Debug_Mode
*
8x 01 39 0q ff
q=0: Debug mode off.
q=1: Debug mode on. Camera sends stdout as

Reboot the camera. This also resets serial speed
to 9600.

Reply is sent before the speed switch takes place.
Please wait 20 seconds after ok before sending
new commands.
