Maybe 25% of the TCP you have is usable.  The ring buffer *has* to go,
but the single fixed transmit buffer can stay, unless you want it to
go fast.  Keep in mind that what you have was designed for Telnet, and
does not work particularly well in even LPR, which sends much more data
that it receives.

You need a 4K window if you want to get good speed out of high-quality
network interfaces.  Single-buffered interfaces like the 3C501 actually
benefit from a smaller window (1 packet worth).
