- For serial ports without a FIFO UART, I experienced little difference between
- stock asy drivers and FAS. Maybe ISC did a better job than their competitors,
- I dunno, the last ISC package I played with is 2.0.1...
-
- However, FAS appears to be much better in exploiting FIFO UARTs than its
- competitors: the asy drivers that come with ESIX 4.0.3 and Dell 4.0.2.0
- failed to reduce the system load noticably when using 16550s.
