You would probably have better luck if
(1) you made the ^O MAGIC_SYSRQ_TRIGGER processing conditional on being 
the console, and not selecting this as the console (or disable it in 
the config), and

(2) changing the inter-character delay to be only on failure.

I have sent files xmodem over another hvc_driver client which had a an 
effective throughput less than 1200 baud.
