[[Protocol]] ATDT commands

I have a modem question : where to put that AT command in my login script ATM0L0 (or ATM1L1 will control volume output)

# file:///etc/chatscripts/provider
'' ATZ
'' ATM
'' ATM1L1

ATM = init bip ?

man chat

Modem : ifconfig ppp0 mtu 576


# lspci

[[HP-Laptop]] ZE4420us

Hi. I have a HP ZE4420us Laptop which has very similar specs to your AmiloA and I have found your pages very useful.

I hope I can help on the modem front. Here's what worked for me.

Don't trust what lspci says

Check via Windows.

Windows says Conexant 56K AC-Link Modem. It's a HSF modem. Check scanmodem etc.

Many references to the conexant (aka linuxant) drivers working, but the free version is limited to 14.4K. Full version will cost you $15.

What I did:

  • The last free of charge drivers are at
  • Downloaded,
  • make install .
  • This created device /dev/ttySHSF0
  • Then run /usr/sbin/hsfconfig
  • This forced a recompile of the drivers and replaced the ones I already had.
  • (note need to edit /etc/wvdial.conf to set to above)

Excellent tips on using terminals with modems (note: need the above setup/init first)

cat /dev/ttySL0 in terminal 1 and
echo "AT" > /dev/ttySL0 in terminal 2

This worked very well.

Si le volume du modem est sur muet, aller modifier le fichier remplacer ATM0L0 par ATM1L1
