Format: nnaaaaa.bb[_dd][\p]
nn is the name or type of the variable
aaaaa is the address of the variable (addresses are in octal)
.bb is the bit number of the variable
_dd is the destination address
\p is an optional protocol or port number (range 1-2)

Note: To specify bits for V, use the form Vaaa.bb, where aaa means the word address and bb means
the bit specification from 00-15. Writing to bits cause a word write.
Note 1:V locations can be interpreted as Signed Integer, Unsigned Integer, or BCD. The normal
interpretation of a V location is Signed Integer. Reading V locations in a different format is done by
adding a colon and a suffix to the V location address.
V100:C Read or Write the contents of V100 as BCD 0000-9999
V100:I Read or Write the contents of V100 as Signed Integer -32767 to 32767
V100:U Read or Write the contents of V100 as an Unsigned Integer 0 to 65535
