I tried to write 0x80 to 0x1002 and 0x101A today. The results are as
the followings:
# ./epp 0x101a
ECR address: 0x101a
initial read: 0x00
write: 0x80
final read: 0x00
# ./epp 0x1002
ECR address: 0x1002
initial read: 0x15
write: 0x95
final read: 0x95
There are no change for the parport modes:

world's best and brightest in the field, creating opportunities for Conference
attendees to learn about information security's most important issues through
interactions with peers, luminaries and emerging and established companies.
