I don't know about a software fix, but I "fixed" the problem by getting a
serial card with a 16650 UART (a TCOM 4-port card... www.byterunner.com
sells a couple of versions, with 1 to 8 ports). I have a patch that
turns on automatic hardware flow control on 16650s, which lets me run two
115Kbaud ports on my 386 (and occasionally two 57Kbaud ports) without any
overruns. Throughput does suffer if the machine is loaded down too much,
but it's much better than losing characters and the other end having to
backoff and retry.

An ESP with it's big FIFO would probably be better, but the 16650 card was
pretty cheap :) The 16650 patch is in PR #3844, BTW...
