Hi, I'm using Ubuntu 7.04 with kernel 2.6.20-16-generic. The patch to slmodem-2.9.11-20070813 from http://helllabs.org/patch/20070710_slmodem/slmodem-2.9.11-alsa-period-size.patch fixed the "error: period size 48 is not supported by playback (64)". However, wvdial now says that there is no carrier. I've tried multiple numbers to multiple ISPs, but still there's no carrier: vlad@ubuntu:~$ sudo wvdial --> WvDial: Internet dialer version 1.56 --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 OK --> Modem initialized. --> Sending: ATDT MY NUMBER --> Waiting for carrier. ATDT MY NUMBER NO CARRIER --> No Carrier! Trying again. --> Sending: ATDT MY NUMBER Following are the contents of /etc/wvdial.conf: [Dialer Defaults] Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 Modem Type = Analog Modem Phone = MY NUMBER ISDN = 0 Username = MY USER Init1 = ATZ Password = MY PASSWORD Modem = /dev/ttySL0 Carrier Check = no Baud = 460800 The problem I'm encountering seems to be the same as in: http://archives.linmodems.org/27282 Any idea how to get wvdial to recognize the carrier?
