bool "Print bytes sent/received over OSDP to console"
help
Prints bytes sent/received over OSDP to console for debugging.
LOG_HEXDUMP_DBG() is used to achieve this and can be very verbose.
config OSDP_SKIP_MARK_BYTE
bool "Skip sending the initial marking byte (0xFF)"
help
As per the OSDP specification, the first byte in the channel has
to be a MARK byte which is 0xFF. Since this is not stated in the
packet structure definition, some commercial CPs and PDs do not
handle the initial mark byte correctly. This option can be used to
completely disable sending/expecting a mark byte to work with
such non-conforming devices.
