The last few lines look like this:

:06 04 02 0F DD C6 B4 F0 08 C9
:BB D0 04 A0 1D A2 00 4C FF B1
:B7 00 00 00 8D 63 AA 8D 70 AA
:8D 71 AA 60 20 5B A7 8C B7 AA
:60 20 7E AE AE 9B B3 9A 20 16
:A3 BA 8E 9B B3 A9 09 4C 85 B3
:
3D0:4C BF 9D 4C 84 9D
3F2:BF 9D 38 4C 58 FF
3F8:4C 65 FF 4C 65 FF 65 FF
9D84G

The last 4 lines put the jump vectors back in then call the DOS cold start
routine.
$3DO - jmp to dos cold start, jmp to dos warm start
$3F2 - Reset handler, checksum, Applesoft & handler
$3F8 - Jmp-Ctrl-Y,NMI and IRQ

If this is isn't what you're seeing on screen then I can only presume you
have some sort of comms problem, it might be worth trying a small inter
character delay. The inverted L and P sound like that might be the problem.
