Uploading Serial Data
General:

supports serial port connections.
2. Commands are not case sensitive.
3. Each command is starts with '$' sign and is ended with <CR><LF>(Enter).
4. There are no spaces inside command.
5. Every command which needs a parameter can be used to enquire the current setting of the
parameter by entering the mnemonic command by itself (rule 2 applies).
For example:
$MM,2<CR><LF> sets the Measurement Mode to 2 (SD)
$MM<CR><LF> returns value 1 (current Measurement Mode setting).
