RE: what serial port type are Elan ports?

[Alex Pavloff <apavloff@eason.com>]

Hi Ed,

Well, here's the output from my stock Red Hat 7.3 (2.4.18-3) system, running
on an AMD ElanSC520-133AC Alpha Rev 1A from 1999 (antique, aint it?).  Its
sitting on an AMD Aspen Microcontroller Customer Developer Platform Rev 1.2.

serinfo:1.0 driver:5.05c revision:2001-07-08
0: uart:16550A port:3F8 irq:4 baud:9600 tx:11 rx:0
1: uart:16550A port:2F8 irq:3 baud:9600 tx:11 rx:0
2: uart:unknown port:3E8 irq:4
3: uart:unknown port:2E8 irq:3
4: uart:unknown port:1A0 irq:9
5: uart:unknown port:1A8 irq:9
6: uart:unknown port:1B0 irq:9
7: uart:unknown port:1B8 irq:9
8: uart:unknown port:2A0 irq:5
9: uart:unknown port:2A8 irq:5

Is this what you need?
