[hsflinux] modem hangs up in few minutes

Mon Jun 30 20:49:18 EDT 2003

Hi, Jean_Simon:

I have tried again to use Dana Lacoste's script to connect internet (using 
Konquerror as browser), the modem hang up in a couple minutes. The following 
is the message after I run the command: cat 
/proc/driver/hsf/0/lastcallstatus  right after getting disconnected:
