The g-protocol spoofing is neat, but here is a thought:  Would it be
worthwhile to write an `h' protocol, specifically designed for
half-duplex high-speed not-necessarily-error-free modems?

	- large packets (perhaps 4KB);
	- a window of at least 256 packets;
	- checksums per packet, but
	- ACKs not required except at EOF or window edge
	- with NAKs accepted anytime;
	- characters ^Q and ^S reserved to the modem,
	  with an escape encoding in the data stream

I doubt it would make much difference on the TB+, but it might help
other half-duplex 9600/19200/38400 bps modems.

(And no, I do not volunteer to write it. :-) )
