Error messages
The K-LD2 responds with a message from the table
below ifanerror has occurred.
Command Format
Every command is ASCII coded and needs to be sent
over the serial interface by a host CPU or an ASCII
terminal program. Every request needs to start with
the prefix $ and ends with a <CR> (0x0D in Hex). The
K-LD2 always answers with @ as a prefix excluding the
command class C.
