The BSD implementation uses a ridiculous 'assume 4K is a good initial window' scheme, totally invalidating what little credibility is left with the protocol
I found hacking BSD to use 2*MSS was needed to make T/TCP even work on 1200 or 9600 half duplex links

Note T/TCP and UDP have the same number of transactions for the same reliability level.
