+This command enables or disables the use of the @samp{qOffsets}
+request packet. This packet is used to find a relocated downloaded
+image. @xref{General Query Packets, qOffsets}, for more details about
+this packet. The default depends on the remote stub's support of this
+packet (@value{GDBN} queries the stub when this packet is first
+required).

+@cindex supported packets, remote query
+@cindex @samp{qPacketInfo} packet
+Tell the remote target about features supported by @value{GDBN}, and
+query it for features it supports.
+
+No values of @var{feature} are defined yet. Targets should ignore any
+unknown values for @var{feature}. Any @value{GDBN} which sends a
+@samp{qPacketInfo} packet supports receiving packets of unlimited
+length. Values for @var{feature} may be defined in the future to let
+the stub take advantage of new features in @value{GDBN}, e.g.@:
+incompatible improvements in the remote protocol.
+
+The reply is one or more feature responses, or empty if this packet is
+not supported. Multiple feature responses are separated by semicolons,
+and individual feature responses may not include semicolons. @value{GDBN}
+will silently ignore unrecognized feature responses, as long as the
+unrecognized response has one of the standard forms. The standard forms
+are:
+
+@table @samp
+@item @var{name}=@var{value}
+Set a remote communication parameter to the specified value.
+@item @var{name}+
+The remote protocol packet @var{name} is supported.
+@item @var{name}-
+The remote protocol packet @var{name} is not supported.
+@end table
+
+Currently only one communication parameter is supported:
+
+@table @samp
+@item PacketSize=@var{bytes}
+The remote target can accept packets up to at least @var{bytes} in
+length.
+@end table
+
+The name of a packet which can be marked as supported or unsupported
+is the text of the packet in this documentation, up to but not
+including the first punctuation character or variable. For example, a
+target which supports hardware watchpoints but not hardware
+breakpoints might report @samp{Z0-;Z1-;Z2+;Z3+;Z4+}. An exception is
+made for @samp{qPart:@var{object}} packets; the name of the packet
+includes the @var{object}, but not the @var{annex}. Individual
+@samp{qPart} packet types must be reported separately.
+
+Currently, all remote packets which are not mentioned in the response
+will be probed individually, just as if the @samp{qPacketInfo} command
+was not supported. In the future, some new packets may be added to
+the remote protocol which will be assumed to be unsupported unless
+@samp{qPacketInfo} is supported and the new packet is reported in the
+@samp{qPacketInfo} response.
