How to tell gdb to exit?

I'm trying to figure out how to run gdb from a shell script,
and everything works, except I can't get gdb to exit. What I
want to do is:

1) set target to /dev/ttyS0
2) load an elf file
3) start it (continue)
4) exit gdb

Steps 1-3 work great, but at step 4) gdb won't accept a new
command in human-interface mode, so this doesn't work:

#!/bin/bash
h8300-elf-gdb <<EOF
set arch h8300h
target remote /dev/ttyS0
load test.elf
cont
quit
EOF

I tried "detach" instead of "cont" since the info file says
that it continues exection, but it doesn't actual seem to do
that for remote targets.

In MI mode, I can't figure out what the "quit" command is, and
it just hangs on EOF -- so this doesn't work either:

#!/bin/bash
h8300-elf-gdb -interpreter=mi <<EOF
10-target-select async /dev/ttyS0
20-target-download test.elf
30-exec-continue
EOF

I'm sure I'm missing an obvious clue, could somebody point it
out to me?
