where pri-addr is a two-digit primary
address in the range from 00 through 30 and
sec-addr
is a two-digit secondary address
from 00 through 31. Numeric addresses
must be given as two-digit numbers, e.g. 05
for address 5, and 1601 for primary address
16, secondary address 1
[ ,addr…] An optional list of bus addresses, each one
preceded by an address separator; either a
comma (,) , a slash (/) or a period (.).
No more than 15 bus addresses are allowed in
any single command.

5.2.1.3 ASCII Characters
$char A single character whose ASCII value is the
