USB ISDN NT device
This message was originally posted to Networking subfoum, please excuse me for duplicating.
I've got a Sphairon NT1+web ISDN modem with USB interface. It works well in Windows, but I cant make it work in Linux.
when I plug it to Linux machine, I see this in /var/log/messages:
Aug 13 12:42:20 cruter kernel: hub.c: new USB device 00:02.0-1, assigned address 5 Aug 13 12:42:20 cruter kernel: ttyACM0: USB ACM device Aug 13 12:42:24 cruter /etc/hotplug/usb.agent: Setup acm for USB product 114b/22/1 Aug 13 12:42:24 cruter /etc/hotplug/usb.agent: Setup acm for USB product 114b/22/1Code:

[Dialer Defaults] Modem = /dev/modem Baud = 230800 Init1 = AT Init2 = AT&F&D2&C1V1E0S0=0 Init3 = ATS30=0 Init4 = ATS0=0 Dial Command = ATD Phone = 633333 Username = *** Password = ***
# wvdial --> WvDial: Internet dialer version 1.53 --> Cannot open /dev/modem: Invalid argument --> Cannot open /dev/modem: Invalid argument --> Cannot open /dev/modem: Invalid argument
# wvdial --> WvDial: Internet dialer version 1.53 --> Initializing modem. --> Sending: AT --> Sending: ATQ0 --> Re-Sending: AT --> Modem not responding.
It seems that /dev/modem is working correctly, but initialization string is not correct. My problem also is that I cant check modem by sending AT-commands through terminal - modem does not respond on any command even in Windows Hyper Terminal, but works fine. Those strings in my wvdial.conf I copied from COM3 log dump after successful Windows connection session (modem has answered "OK" to every initialization string in this dump).
Please give me some advices.
Sorry for my bad English.
