Cool lsof of the iLiad

lsof is a tool that lists all the files open by all the processes on a system. In Unix just about everything is a file, so things like socket connections used to talk from one program to another also appear in this listing.

It is in essence a "map" of how the iLiad is plumbed together.

I just call it hacker snacks.

Enjoy.

beats me, but why do I still think that the ominous unused pins on the connector are a serial console?
(to bad I have to much fear of bricking the iLiad if I would try to figure it out, especially since I lack the needed tools and knowledge.)

There is definitely an active serial port with a login program waiting patiently for someone to login in.

Code:
root@ereader:/usr/bin# ps -ef
root       691     1  0 00:35 ttyS2    00:00:00 /sbin/getty -L ttyS2 115200 vt100
It is hooked to /dev/ttyS2

Code:
root@ereader:/usr/bin# ls -l /dev/ttyS2
crw--w--w-    1 root     root       4,  66 Oct 25 00:35 /dev/ttyS2
Driver information from /proc.

Code:
root@ereader:/proc/tty/driver# cat serial
serinfo:1.0 driver:5.05c revision:2001-07-08
0: uart:PXA UART port:F8100000 irq:15 baud:19200 tx:4 rx:5159 RTS|CTS|DTR|DSR|CD|RI
1: uart:PXA UART port:F8200000 irq:14 tx:0 rx:0 
2: uart:PXA UART port:F8700000 irq:13 baud:115200 tx:13308 rx:0 RTS|DTR
The tx count goes up over time as the getty program times out and re-issues the login prompt.

My guess is that UART #0 is the Wacom interface.
