Any other newsgroup server access over port 80? Afaik, google is the

There are quite a number of them.

So, when you're behind a "firewall" blocking every port except 80 you
have no choice.

Inquire why port 119 is being blocked. Some entities block it because
of abuse, and get unhappy if the firewall is bypassed.

That's an external modem, and it has DIP switches, right?

This one seems to be newer. It's completely sw configurable.

Have to love how they save money by not including hardware ;-)

According to the spec I can set the modem to "Message mode" off via
"at +mcs=0", i.e, "message control switch" is off, but, after the next
"atz" and switch off and on again it will be "1".

Yeah, that's two problems. The 'NVRAM' settings (what "ATZ" resets
the modem to) can be altered, using the "AT&W0" command. If you have
access to 'minicom' (or 'seyon' or any other terminal software), you
can run through the following steps:

AT&F0 reset the modem to factory defaults
AT+MCS=0 set message control "off"
AT&W0 save the settings to NVRAM register 0
AT&F0 reset the modem to factory defaults
ATI4 display current settings - message control will be on
ATZ reset the modem to NVRAM setting 0
ATI4 display current settings - message control will be off

Do NOT use the AT&W command often - NVRAM has a limited (thousands)
number of write cycles. NOTE: Read the manual and verify the
commands I show here. Not every modem follows the same set of commands.
Note also that modem commands are not case sensitive - ATZ = atz.

Second problem - on startup, the modem resets. I'm not a Mandriva
user, but you want to look in the boot scripts, probably located in
/etc/rc.d/ - there should be a file named rc.local. This is the
last boot script to run. You can probably insert the following command
in that script

echo "AT+MCS=0" > /dev/modem

correcting the '/dev/modem' to where ever your modem is hiding.

So, whenever KPPP makes a dial up internet connection and therefore
resets the modem by sending "atz" the the next day when powering on
the machines the modem is in "answering machine" mode again.

Yup - _NORMALLY_ I do not recommend using 'atz' as the modem init
string, because often the user has no idea what may have been stuffed
into NVRAM (the "safe" recommendation is to use the AT&F0 to reset the
modem to factory defaults), BUT IN THIS CASE, if you've managed to
follow the string of commands to set NVRAM to disable the "answering
machine" mode, that 'ATZ' will now set the modem to "answering machine
off" mode. An _alternative_ is to kick KPPP between the eyes and
tell it to use a different init string - ATZ (or AT&F0) first, and
AT+MCS=0 for the second init string.

I don't know how to come around that.

There are several ways - above I suggest two that should work for you.
