I am fairly to FreeBSD (and any kind of Unix), so please be easy on me in case I'm overlooking the obvious. :) I've been trying to connect to my ISP with an external "Elsa Microlink ISDN/TL pro" modem. The init string that the modem requires is AT&F\N9. I modified the following line in /etc/ppp/ppp.conf: set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \ \"\" AT OK-AT-OK AT&F\\N9 OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT The man page for chat (http://www.freebsd.org/cgi/man.cgi?query=chat&sektion=8) says that \\ sends a backlash character, so I figured that AT&F\\N9 would be sent as AT&F\N9. However, it doesn't seem to send a backslash. Here's the relevant bit from /var/log/ppp.log: Sep 1 15:01:36 catbox ppp[372]: tun1: Chat: deflink: Dial attempt 1 of 1 Sep 1 15:01:36 catbox ppp[372]: tun1: Chat: Send: AT^M Sep 1 15:01:36 catbox ppp[372]: tun1: Chat: Expect(5): OK Sep 1 15:01:37 catbox ppp[372]: tun1: Chat: Received: AT^M^M Sep 1 15:01:37 catbox ppp[372]: tun1: Chat: Received: OK^M Sep 1 15:01:37 catbox ppp[372]: tun1: Chat: Send: AT&FN9^M Sep 1 15:01:37 catbox ppp[372]: tun1: Chat: Expect(5): OK Sep 1 15:01:37 catbox ppp[372]: tun1: Chat: Received: AT&FN9^M^M Sep 1 15:01:37 catbox ppp[372]: tun1: Chat: Received: ERROR^M Sep 1 15:01:42 catbox ppp[372]: tun1: Chat: Expect timeout Sep 1 15:01:42 catbox ppp[372]: tun1: Warning: Chat script failed I have also tried this with AT&F\N9, AT&F\\\N9 and AT&F^\N9. I'm unsure why the script expects "timeout" and not "CONNECT". If I leave out "AT&F\\N9 OK" before ATE1Q0, the modem will dial (the LNE LED indicates that an ISDN connection is being established), but won't get a carrier. In this case the log looks like this: Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: deflink: Dial attempt 1 of 1 Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: Send: AT^M Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: Expect(5): OK Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: Received: AT^M^M Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: Received: OK^M Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: Send: AT&F^M Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: Expect(5): OK Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: Received: AT&F^M^M Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: Received: OK^M Sep 1 14:58:43 catbox ppp[359]: tun1: Chat: Send: ATDT019102345^M Sep 1 14:58:45 catbox ppp[359]: tun1: Chat: Expect(40): CONNECT Sep 1 14:58:45 catbox ppp[359]: tun1: Chat: Received: ATDT019102345^M^M Sep 1 14:58:45 catbox ppp[359]: tun1: Chat: Received: NO CARRIER^M Sep 1 14:58:45 catbox ppp[359]: tun1: Warning: Chat script failed Any help is greatly appreciated.
