 So that could explain why after the "g" command, you see a "p"
 command and I get a "m" command?

 Just retested everything with NetBSD-7.99.20/amd64 on both ends.

 The target architecture is set automatically (currently i386)
 
 I just tried the following .gdbinit, but got the same uninitialized
 lock panic:

 set serial baud 9600

 show architecture

 (again the "m" command as per protocol.txt:
