SR - Status Register
Purpose:
Returns a bit-field, reporting the status of the system in a concise format. Most of the
information in SR may be recovered using other commands. The primary purpose of
the SR command is to enable a remote host — such as the Composer program — to get
a snapshot of the system status without overloading the communications system.
