Output

-1.0000 -1.0000 2D 31 2E 30

30 30 35

As can be seen above, positive input numbers use
the ASCII “+” whilst the output will use a “sp”
space character to represent a positive number.
Negative numbers are identical for both input and
output.

Combining
Commands

Commands and queries can be combined to form a
large continuous command.
Each command must be separated with a line feed
character< ^END>(or <^J>). The combined
command must be terminated with a line feed and
carriage return character< ^END^M>(or <^J^M>).
All messages and parameters will be returned
sequentially with a line feed character (< ^END>(or
<^J>

)separator.
