# SpeedTouch Configuration for Alcatel USB Modem

# Tested on RedHat 8.0 with BT OpenWorld by Steve
# Tested on Mandrake 9.0 with BT OpenWorld by Steve
# Updated 29 Oct 2002 to create a log file for diagnosis.
# Updated 21 Nov 2002 to list Singapore Pacificnet VPI/VCI pair.
# Updated 25 Nov 2002 to use "tar -xzf" not "tar xzf" as one user reported problems.
# Also added a web page (http://www.japarker.btinternet.co.uk/speedtouch/)
# Updated 03 Dec 2002 - moved to http://speedtouchconf.sourceforge.net/
# btinternet.co.uk site deprecated.
# Updated 05 Dec 2002 - creates symlink to /etc/ppp/resolv.conf to fix DNS problems.
# Also includes speedtouch-1.1.tar.bz2, accepts microcode in current directory as
# speedmgmt.tar.gz, mgmt.o, or alcaudsl.sys. Therefore no need to edit the script.
# Updated 07 Dec 2002 - fixed a bug that it couldn't find the tarball.
# Updated 17 Dec 2002 - added uname -a to logfile, added tests for gcc, make
# Updated 23 Dec 2002 - specified GPLv2 after reading http://www.infoworld.com/articles/hn/xml/02/11/06/021106hngnudelay.xml?s=IDGNS
# Version 08 Jan 2003 missing a "fi" - fixed 15/1/2003
# 16 Jan 2003 - fixed another stupid bug.
# 19 Jan 2003 - Actually did some decent testing, and got it working again. Also added a comment about the timeout messages.
# 20 Jan 2003 - Just some extra checks.
# 23 Feb 2003 - Allows for init.d being /etc/init.d/ or /etc/rc.d/init.d
# Also some basic checks for the kernel-level driver. First tidy-up of the kernel testing code, too.
# 07 Mar 2003 - Some SuSE (LSB) tidyups; skip debian-specific notes for non-debian users
# 11th August 2003 - Changed to stop if gcc/make/etc are not installed. Also bundled the 1.2beta2 driver.
# 18th August 2003 - Tidied up the output a little bit to make it clearer.
# 9th September 2003 - Fixed speedtouch-init for RedHat 9
# 11th September 2003 - Added 2.6 support; tidied up the kernel checks a bit.
