Okay, then I do understand. My advice of using PPP should be fine then. You just have to add somme AT commands you need. PPP can issue them instead of dialing a number and then establish the connection. -- Polytropon From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

You could try to leave it to ppp, just for testing purposes. Everything you need is a number you can dial. Here's an example for an /etc/ppp/ppp.conf that would do something like this: # --- ppp.conf --- default: set log Phase Chat LCP IPCP CCP tun command ident user-ppp VERSION (built COMPILATIONDATE) set device /dev/cuad0 set speed 115200 set dial ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \\ AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT set timeout 120 enable dns papchap: set phone PHONE_NUM set authname USERNAME set authkey PASSWORD add default HISADDR test: set phone 0123456789 set authname QWERTZ set authkey ASDFGH add default HISADDR # --- ppp.conf --- end --- With such a file, you can now: # ppp test ppp dial *click dit dit dit dit... do doo... * PPP close *click* ppp # In this case, you have confirmed that the serial modem works as intended. You can of course enter real data for an ISP that offers modem dial-in to get online. :-) You can find more help and examples in man ppp. the modem has 2 leds. one yellow and one green. according to the manual the yellow should be blinking as follows: Fast Blinking (0.5 sec on/0.5 sec off) Net search/ Not registered/Turning Off Slow Blinking (0.3 sec on/ 2.7 sec off) Registered, Full Service i think i'm only seeing 'Fast Blinking'. i wonder what 'Net search' really means and where it's searching for it. it's connected through a RS-232 to the serial port... ?!?

outbound serial modem now times out or drops connection
We are using qpage to dial a remote TAP modem (Sprint and Verizon), so we can send pages about our hosting infrastructure without using the internet connection. Recently it started failing consistently with timeout to connect. I first suspected the remote modem (Sprint), but found I got the same result with other carriers. (And Sprint denied a problem on their end). I have since tried a whole battery of approaches including having the phone line checked by the local phone company, trying a different modem and trying a different phone cord. Trying a new modem (US Robotics external 56k serial modem) did help slightly. With it, we consistently connnect, but then after a short pause the connection is dropped. This is easily reproduced in minicom: (Using the Sprint TAP modem number here). ATDT18886561727 CONNECT 31200/ARQ/V34/LAPM/V42BIS NO CARRIER I'm out of ideas here. This phone line is only used for this outbound service, although our alarm system also uses it for outbound alerts. Any suggestions for possible causes or further troubleshooting approaches are appreciated. Thanks!

I tried that with Minicom, and the prompt just goes back to the hover over the # sounds and sits there. From some quick Google searches, I didn't find any mentions of this modem supporting that. I'm also not familiar with the details of the TAP protocol. After the CONNECT, who should speak next? From looking at the qpage source code, it looks like we might be waiting for ID= to sent from the remote end, and it is not. That would make me suspect the remote end, except that multiple remote modems are responding the same way.

Mark Mark, The only tap I am familiar with is /dev/tap virtual Ethernet device, as I am currently working on a project that makes use of this interface. Since you get the connect message from your modem, they were able to negotiate a reliable connection. So you have to assume that you do not have any phone line issues. Then it becomes a matter of seeing the correct handshake sequence between the two systems. I would expect the answering system to start that conversation. The NO CARRIER message suggests that the other end dropped the connection, or hung up on you instead of sending the opening message. That should be worth filing a trouble report. Is it possible that those serial ports have been disabled, or that process has been shut down? It is possible the process died without disabling the auto-answer status of the modem. Some of those modems are just too smart for their own good. Please do not CC me on this thread. I can read it just fine from the list.

cendyne 56k external serial modem?
Howdy list, I've been looking for a cheap external v.90 56k lately so I can go ahead and convert my home computer to FreeBSD (has a winmodem currently). I found the cendyne 56k modems all over the internet for about $20, sometimes even including shipping. I think Cendyne went out of business or something. Anyway, I'm just wondering if the cendyne 56k is indeed a controller based serial modem, or if it's a nasty serial winmodem, designed to fool the world into thinking it's controller based. Has anyone had experience with the cendyne external 56k serial modem? -- Jesse Guardiani, Systems Administrator WingNET Internet Services, P.O.
