Redboot half-duplex protocols


Hi everyone,

I am currently communicating with my Redboot board using X/Y modem and
tftp  through full-duplex over RS232, but eventually need to move (or at
least be able to support) half-duplex over RS485. As far as I can see
that's all there is available for Redboot (in addition to tcp/ip which
also requires full-duplex) but what are people doing for half-duplex
comms. I realize that I can always write my own, but I am curious to see
if there are already solutions out there that people are using.
