The following set and query packets have already been defined.

fThreadInfo
– all thread idsq
sThreadInfo
Obtain a list of active thread ids from the target (OS). Since there
may be too many active threads to fit into one reply packet, this query
works iteratively: it may require more than one query/reply sequence to
obtain the entire list of threads. The first query of the sequence will
be the qf
ThreadInfo
query; subsequent queries in the
sequence will be the qs
ThreadInfo
query.
NOTE: replaces the qL
query (see below).

'In response to each query, the target will reply with a list of one or
more thread ids, in big-endian hex, separated by commas. GDB
will respond to each reply with a request for more thread ids (using the
qs
form of the query), until the target responds with l
(lower-case el, for 'last'
).

sym_value:sym_name message, described below.
qSymbol:
sym_value:sym_name — symbol valuesym_name (hex encoded) is the name of a symbol whose value the target has previously requested.
sym_value (hex) is the value for symbol sym_name. If GDB cannot supply a value for sym_name, then this field will be empty.
