2.2.1 Instruction Set
Communication with ARE i2.0x SEMI is based on a simple ASCII text based protocol. The host sends text based telegrams to
ARE i2.0x SEMI and receives text based telegrams back containing the answer to the query. Communication to ARE i2.0x
SEMI is always triggered by the host.

The protocol format is as follows
Instruction <CR> for instructions without parameter
Instruction <SP> parameter <CR> for instructions with only 1 parameter
Instruction <SP> parameter <SP>data<CR> for instructions with parameter and data
The space character <SP> separates commands from parameters and data and the <CR> character acts as command line
terminator.
