A USB-modem works via ubsa.ko This device need to catch NO CARRIER to disconnect correctly. WinXP does it with lowering DTR to 0. In ppp.conf is following evdo: set device /dev/cuaU0 set speed 115200 set mru 1400 set mtu 1400 set timeout 160 disable mppe set phone \#777 set dial "ABORT BUSY ABORT ERROR ABORT NO\\sCARRIER TIMEOUT 5 \"\" ATZ OK AT OK "ATE0V1&F&D2&C1S0=0" OK ATX1 OK AT OK \\dATDT\\T TIMEOUT 40 CONNECT" set logout "ABORT BUSY ABORT ERROR ABORT NO\\sCARRIER TIMEOUT 30 \"\" ATH\\sE1 OK" set authname bwc set authkey bwcbwc set login set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0 add default HISADDR All AT-commands got from windows driver. It is working good, but when I disconnect with killing ppp it doesn't disconnect and write this to log.
