The following patches support remote process debugging on hp-ux (hp9k320).  
These patches only support the form of attach where a device file is specified
for remote communication.

These patches are for gdb3.0 :

1) hp9k320-dep.c   Addition of attach and detach routines.
2) m-hp9k320.h     defined ATTACH_DETACH
3) remote.c        Numerous generic bug fixes applicable to all machines.

Thanks for including these in the next release,
