	I'm using the remote facilities provided by GDB, but am encountering
	problems with the GETPKT and PUTPKT routines. I occassionally get
	BAD CHECKSUM errors. These errors are consistent in that the check-
	sum calculated at the receiving end is almost the same apart from the 
	top bit which is always set.

	Sent Checksum				Calculated Checksum

	    0x1a					0x9a
	  00011010				      10011010
						      ^
						      This is the only bit
	that is different. The routines at both ends of the transfer are
	those from REMOTE.C. Is there a bug in these routines? I've been 
	through them and can't see anything obvious. I'm using V3.1.

	I would welcome any help or advice?

	Thanks

	Kaush.
