Set the use of the remote protocol's @samp{qXfer:auxv:read} (target
auxiliary vector) request. This request is used to fetch the
remote target's @dfn{auxiliary vector}, see @ref{OS Information,
Auxiliary Vector}. The default setting depends on the remote stub's
support of this request (@value{GDBN} queries the stub when this
request is first required). @xref{General Query Packets, qXfer}, for
more information about this request.
@item show remote read-aux-vector-packet
Show the current setting of use of the @samp{qXfer:auxv:read} request.
@item set remote symbol-lookup-packet
@cindex remote symbol lookup request
Set the use of the remote protocol's @samp{qSymbol} (target symbol
lookup) request. This request is used to communicate symbol
information to the remote target, e.g., whenever a new shared library
is loaded by the remote (@pxref{Files, shared libraries}). The
default setting depends on the remote stub's support of this request
(@value{GDBN} queries the stub when this request is first required).
@xref{General Query Packets, qSymbol}, for more information about this
request.
@cindex remote packets, enabling and disabling
The @value{GDBN} remote protocol autodetects the packets supported by
your debugging stub. If you need to override the autodetection, you
can use these commands to enable or disable individual packets. Each
packet can be set to @samp{on} (the remote target supports this
packet), @samp{off} (the remote target does not support this packet),
or @samp{auto} (detect remote target support for this packet). They
all default to @samp{auto}. For more information about each packet,
see @ref{Remote Protocol}.
@item show remote symbol-lookup-packet
Show the current setting of use of the @samp{qSymbol} request.
@item set remote verbose-resume-packet
@cindex resume remote target
@cindex signal thread, and remote targets
@cindex single-step thread, and remote targets
@cindex thread-specific operations on remote targets
Set the use of the remote protocol's @samp{vCont} (descriptive resume)
request. This request is used to resume specific threads in the
remote target, and to single-step or signal them. The default setting
depends on the remote stub's support of this request (@value{GDBN}
queries the stub when this request is first required). This setting
affects debugging of multithreaded programs: if @samp{vCont} cannot be
used, @value{GDBN} might be unable to single-step a specific thread,
especially under @code{set scheduler-locking off}; it is also
impossible to pause a specific thread. @xref{Packets, vCont}, for
more details.

@cindex remote hardware breakpoints and watchpoints
These commands enable or disable the use of @samp{Z} packets for
setting breakpoints and watchpoints in the remote target. The default
depends on the remote stub's support of the @samp{Z} packets
(@value{GDBN} queries the stub when each packet is first required).
The command @code{set remote Z-packet}, kept for back-compatibility,
turns on or off all the features that require the use of @samp{Z}
packets.

@kindex set remote get-thread-local-storage-address
@cindex thread local storage of remote targets
This command enables or disables the use of the @samp{qGetTLSAddr}
(Get Thread Local Storage Address) request packet. The default
depends on whether the remote stub supports this request.
@xref{General Query Packets, qGetTLSAddr}, for more details about this
packet.
During normal use, you should not have to use any of these commands.
If you do, that may be a bug in your remote debugging stub, or a bug
in @value{GDBN}. You may want to report the problem to the
@value{GDBN} developers.
