Here's an explaination of "how modem_run works"
1 - start
2 - find the modem
3 - Upload the code
4 - forks
Parent Instance | Child instance
--------------------------------+--------------------------------------------
5 - enters into pause | 5' - open a special endpoint of the modem
| called interrupt endpoint (interrupts
| sent by the modem)
| 6' - Waits until an interupt is read
| 7' - if interrupt == "up" string/constant
<-------------------------------+ then wakeup the parent process else
6 - The child has set the up | loop to 6'.
variable through the signal |
USR2 | We wake up the parent only once, other
handler. | interrupts are just logged in order to
7 - Get the connection speed and| get some infos that could help us to
log it | understand the modem's internals.
8 - quit | This child is the backgrounded modem_run

I think we should add a timemout value in the parent process setting up
an alarm event on USR2 signal. No ? It's just a work around but as
modem interrupts are generated by the alcatel's firmware, we can not
reasonably solve this problem.

Any objections for this "new" feature/woraround ?
Source code is suposed to be frozen in rc :( else i can post a temporary patch
and release a 1.1.1 a few days after the 1.1 ?
What do you guys think about this ?
(1.1 final is planned for Friday 24th around 10pm GMT+1)
