Message closing character
:

Multiple commands can be
chained in the same string. Each command is delimited by a pipe character
(

). When chaining commands, enter the message starting character and
the message closing character only at the beginning and end of the string.
Spaces between parameters or command terms are ignored.
Commands in the string do not execute until the closing character is
entered. A separate response is sent for every command in the
chain.

Some commands have short name syntax in addition to long name syntax to
enable faster typing. The response is always in long syntax.
The Protocol 3000 syntax is in the following format:
