Try typing in the "w" lines manually and see what happens. I have seen
cases where the '+$qOffsets#4b' came in too fast for the target to
handle. If this works manually, try generating the target code to run
at a different baud rate, say 19200, instead of 38400. Then in GDB you'll
need to try:
(gdb) set remotebaud 19200
(gdb) tar rem /dev/XXX
