This is interesting. I'd never heard of setting a manual window size
on any version of Unix. All the ones I'd used before had reasonable
defaults for the TCP window size. Why doesn't Linux? Why make
everybody figure it out for themselves?

This is true enough for 2.0 kernels. I just recently moved to the 2.1
kernel set, because I needed support for a 16650 UART serial port, which
2.0 doesn't seem to support at all (at least, not using the FIFO's on
the chip). In 2.1, when I use the "setserial spd_vhi" command, the
console spits out that the use of this command is "deprecated".
However, I don't see what I am supposed to do instead! So, how do you
set a fast serial rate in the 2.1+ kernels?
