CRC = CRC-16 checksum (3 characters)
The checksum is preferred, but not required. If the checksum is used, the first character is an ASCII “V” followed
by the low and high bytes respectively of the computed CRC 16 checksum (the checksum characters are not
necessarily ASCII). The checksum is to be computed on all characters after the initial <start> character up to,
and including, the first “V” character in the CRC section. If the checksum is not used, the 3 characters should be
ASCII “NNN” (they must be uppercase).

PARM is one or more characters, and is command specific.

The command syntax for Terminal Mode is the same as above with the following modifications:
1) Commands should not have an initial asterisk
2) The CRC is ignored
3) The maximum length is 49 characters
4) All commands are parsed from left to right. Only the first command on a line is
processed, any additional characters are ignored.
