As of the last time I investigated this, the TTY driver on SVR3.2.2
didn't have HFC.  The only way to do this is to replace the TTY driver
with some other TTY device driver, such as FAS.

FAS is a public-domain TTY device driver which, as well as supporting
hardware flow control, also allows FIFO support for the NS16550 UART.
This is important when you're running a modem/terminal at high speeds
without losing characters.

There are some bugs in FAS, so you'd want to keep your eyes open for
new versions.  I'm using it on my 386 though, and it's worth it even
with the few bugs.
