gdb tcp connection closing

[Bill Morgan <arthurwilliammorgan at gmail dot com>]

I'm trying to write a GDB stub for an embedded application

For some reason the GDB host is closing the TCP connection after it
requests qOffsets, and the stub sends an empty reply.

Is that expected?

Here is the entire conversation:
