Read up to 32 bytes. The ESCC *needs* 8, and it doesn't hurt to leave some
...
slop in case there are clone chips with a deeper FIFO.

Make zs_iflush not loop indefinitly. Some Mac PowerBooks lie about having
...
two SCC channels, and can get stuck in an infinite loop. This change
stops after flushing 4 bytes. Might need upping to 8 bytes if we support
85230 ESCC's.

Similar changes to com driver:
...
Arrange to call com_break() and com_modem() at splserial().
It's simpler this way. Really.

Remove the while loop from zsc_intr_hard(). It caused problems on
...
some machines, and those that really want to can just call this
function in a loop until it returns zero.

New version of the z8530 driver that should permit the mac68k port
...
to use this instead of its own. Also fix warnings, etc.

Rename cs_pclk_div16 to cs_brg_clk to clarify the fact that the
...
Baud Rate Generator (BRG) clock is not necessarily PCLK/16.

Make the ring size configurable in the tty driver.
...
Make the pseudo-interrupt functions return void.
Call the tty layer at spltty (to be safe).

Eliminate remaining direct references to the z8530 chip
...
to allow the MD access functions to do delays, etc.

Reorganized, machine-independent z8530 driver, based on the sparc/sun3 zs.
