General Query Packets: custom vendor packets

[Paralkar Anmol-B07584]

Hello,

 Per, E.4 General Query Packets in the GDB User Manual:

 "The names of custom vendor packets should use a company prefix, in lower case,
  followed by a period. For example, packets designed at the Acme Corporation
  might begin with `qacme.foo' (for querying foos) or `Qacme.bar' (for setting bars)."

 How does one get GDB to send a Qacme.bar-packet on the RSP? We need to be able to send
 such a set packet - after doing a 'target remote' and before GDB sends a 'g'-packet.

Thanks,
Anmol P. Paralkar
