Package: linux-image-2.6.22-1-686
Version: 2.6.22-1
Severity: normal
I have a Novatel U630 UMTS card. After I plug it in, I run a "setpin"
script that looks like this:
"""
#!/usr/bin/env perl
use strict;
use warnings;
my $modem = "/dev/ttyS0";
# Substitute xxxx with your PIN.
# You should probably put your pin somewhere else, e.g. on an USB stick,
# an encrypted file system or something else, and read it from there...
# You have been warned!
my $pin = "1234";
$SIG{ALRM} = sub {
die("timeout: no response from modem $modem\n");
};
open(MODEM, "+<", $modem) or die("can't open modem $modem");
alarm(10);
print(MODEM "AT+CPIN=\"$pin\"\n\r");
while (<MODEM>) {
if (m/OK/) {
close(MODEM);
print("PIN accepted\n");
exit(0);
}
if (m/ERROR/) {
close(MODEM);
print("PIN rejected\n");
exit(1);
}
}
"""
With the kernels linux-image-2.6.21-2-686 and linux-image-2.6.22-1-686
I get no response from this and it times out after the given alarm
interval. With the kernel linux-image-2.6.18-4-686 from etch, this works
fine and I get "PIN accepted" after less than a second.
So something was broken along the way. Let me know how I can help debug
this.
