Есть телефон Samsung E-900 с USB дата-кабелем PCB200BBE. Дистрибутив - Fedora Core 6. Ядро Linux fedora 2.6.20-1.2933.fc6 #1 SMP Sat Mar 10 19:15:16 EST 2007 i686 i686 i386 GNU/Linux. Версия pppd 2.4.4

После подключения телефона в /var/log/messages: $ tail -f /var/log/messages Mar 23 18:18:51 localhost kernel: usb 4-1: new full speed USB device using uhci_hcd and address 2 Mar 23 18:18:51 localhost kernel: usb 4-1: configuration #1 chosen from 1 choice Mar 23 18:18:51 localhost kernel: Initializing USB Mass Storage driver...

Телефон на /dev/ttyACM0 нормально опрашивается через minicom. Пробую соединиться с помощью связки pppd + chat script:

root@localhost ppp]# pppd call etk AT OK ATV1S0=0&D2&C1 OK AT+CMEE=1 OK ATS0=0 OK AT&F OK AT+CGDCONT=1,"IP","internet.etk.ru" OK ATD*99***1# CONNECT Serial connection established. using channel 1 Using interface ppp0 Connect: ppp0 <--> /dev/ttyACM0 sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0x7d8d0026> <pcomp> <accomp>] rcvd [LCP ConfReq id=0x1 <asyncmap 0xa0000> <auth pap>] sent [LCP ConfAck id=0x1 <asyncmap 0xa0000> <auth pap>] rcvd [LCP ConfRej id=0x1 <pcomp> <accomp>] sent [LCP ConfReq id=0x2 <asyncmap 0x0> <magic 0x7d8d0026>] rcvd [LCP ConfNak id=0x2 <asyncmap 0xa0000>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] sent [LCP ConfReq id=0x3 <asyncmap 0xa0000> <magic 0x7d8d0026>] LCP: timeout sending Config-Requests Connection terminated. Modem hangup

В чем тут грабли?

Скрипты, с пощью которых соединяюсь:

#/etc/ppp/peers/etk debug modem crtscts /dev/ttyACM0 115200 connect 'chat -v -f /etc/ppp/gprs-etk' #noauth proxyarp nodetach noipdefault defaultroute #default-asyncmap lock novj novjccomp #noaccomp #nopcomp #0.0.0.0:0.0.0.0 nobsdcomp nodeflate ipcp-accept-remote ipcp-accept-local usepeerdns #lcp-echo-interval 0 #lcp-echo-failure 0 user etk mtu 576 mru 576

чат - скрипт: ECHO ON ABORT '\nBUSY\r' ABORT '\nERROR\r' ABORT '\nNO ANSWER\r' '' \rAT #TIMEOUT 12 OK ATH OK ATE1 OK AT+CGDCONT=1,"IP","internet.etk.ru" OK ATD*99***1# CONNECT ''

фал с рар паролями # Secrets for authentication using PAP # client server secret IP addresses etk * etk *

C телефоном Мotorola C-650 эти скрипты работают без проблем
