Dial_up koneksi internet dengan wvdial ... Ada beberapa modem yg mungkin agak susah terkoneksi pada wired connection,, namun jika ketikkan perintah "lsusb" pada terminal si modem tsb ternyata detect,, membingungkan memang... karena gimana mau memulai dial_up kalau modemnya saja blm kelihatan di wired connection... Mungkin dengan dial_up menggunakan wvdial ini bisa membantu untuk berselancar didunia maya :)) ... wvdial sendiri sebetulnya sudah tersedia saat pertama kali kita install di Linux seperti "Archlinux dan Back|track-4" yg pernah saya gunakan... Tapi seperti BlankOn, Ubuntu, Linuxmint belum tersedia.... Jika wvdial belum tersedia bisa diinstall sbb;
Untuk Debian, BlankOn, Ubuntu dan Linuxmint;
#configure wvdial#

Found a modem on /dev/ttyUSB0.
Modem configuration written to wvdial.conf.
ttyUSB0<Info>: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
ttyUSB2<Info>: Speed 9600; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
Seperti contoh diatas ttyUSB yang digunakan adalah ttyUSB0 <<sesuaikan dengan hasil scanning port modem yang kalian gunakan
