openbsd.org man pages case sensitive (was: Re: umts need help)
2009/3/6 Pedro la Peu pe...@am-gen.org: Umsm(4) are commonly pre-configured. I've just noticed that the web-based openbsd.org man pages are case-sensitive.

Re: umts need help
Ouff it is working now ... man that was pain! ;-) Here are some very usefull sites that helped: 1) Sony AT command line reference (very up to date) a really nice pdf !!! http://developer.sonyericsson.com/getDocument.do?docId=65054 2) Here was my problem I needed a AT+CFUN=1 to turn the card on ;-/ http://www.thinkwiki.org/wiki/Ericsson_F3507g_Mobile_Broadband_Module I noticed if I turn off radio afterwards with AT+CFUN=0 or AT+CFUN=4, the gsm card is detached from the kernel: ubt0 detached ucom0 detached umodem0 detached ucom1 detached umodem1 detached umodem2 detached Does someone know if it is possible to re-attach / re-access it without rebooting ? (it is a build-in card, so it is impossible to re-insert it). 3) This page directed me to the Sony AT command line reference. It has some excellent info about the Ericsson MBM F3705g model: http://www.natisbad.org/E4300/Dell_Wireless_5530_AT_cmd_ref.html Here is the working option script: $ cat /etc/ppp/peers/ept debug cuaU0 460800 0.0.0.0:10.64.64.64 netmask 255.255.255.255 ipcp-accept-local ipcp-accept-remote crtscts persist #disable stuff deflate 0 refuse-pap refuse-chap noauth noipdefault nopcomp novj novjccomp connect '/usr/sbin/chat -v -f /etc/ppp/peers/chat/ept3.chat' Here is the working chat script: $ cat /etc/ppp/peers/chat/ept3.chat TIMEOUT 120 ABORT BUSY ABORT ERROR ABORT NO CARRIER ABORT VOICE ABORT NO DIALTONE #enable echo ATE1 #switch modem on OK AT+CFUN=1 # APN OK AT+CGDCONT=1,IP,web.pt.lu # dial OK ATD*99***1# CONNECT \c Thank you all for helping!

Just uncommment these lines, which should already be present, in /etc/syslog.conf: #!chat #*.* /var/log/chat and then do a pkill -HUP syslogd. Stefan

You can search the web for at command set to get information on them. To understand what chat does, read the chat(8) man page. It has a section called CHAT SCRIPT which explains things quite well. I can see the error but, what's wrong in the chat file: ABORT BUSY ABORT NO CARRIER ABORT VOICE ABORT NO DIALTONE ATZ OK AT+CPIN=9907 OK AT+CGDCONT=1,IP,web.pt.lu OK ATDT*99***1# 'CONNECT' '\c' 'TIMEOUT' '5' The script looks good to me, but I'm certainly not an expert. I used a similar script once with a umts modem and it worked. I had AT instead of ATZ though, and I didn't need the PIN, else pretty much the same. Stefan

Unfortunately these AT commands are chinese to me, ... Wow, people don't know modems anymore. Here is a fair description of the hayes command set: http://en.wikipedia.org/wiki/Hayes_command_set You should definitely experiment. Use tip. Just because the company went bust doesn't mean you should leave this to the chinese. You should pay particular attention to how the AT command prefix operates, the use of +++, and on-hook vs. off-hook oeration. You might also care about S registers and dial strings, but those vary. If this were a real modem I'd suggest listening to the speaker too. The time temperature lady used to be a good choice for this. The general problem you want to solve is: given any state this device might be in when you connect, get to a known state, then get it to whatever final state. So, some states the device might be in: online connected offline connected offline idle offline connected, at issued offline idle, at issued (and if you want to be particular, offline 'a' issued is also a state.) the stuff you had in your chat script (and other parts of the hayes command set) is supposed to deal with various cases, so, some common choices, (1 second delay)+++(1 second delay) if the modem is online, go offline. (you'll need to include a delay, and you'll have to suppress the trailing cr to make this work with chat.) \rATZ\r if the modem had previously gotten an at prefix, issue a null command. then reset the modem, which will hang up, and restore initial settings. In the case of your ERROR message - probably something had previously managed to issue AT but hadn't sent a trailing \r. -Marcus Watts

Unfortunately these AT commands are chinese to me, ... Wow, people don't know modems anymore. Yup, I've never had to deal with them much either. The first time I ever had to configure something that talks AT was with UMTS. I still don't know how I managed to get it going back then, and when I tried again recently with a different modem and ISP I couldn't get it to work anymore (I got no IP from them in the IPCP session for some reason, just DNS servers). The basic every-day networking skillset in my world involves wireless and VPNs, not modems. I still know some people my age who know this stuff though, so not all is lost just yet, don't worry :) Stefan
Re: umts need help
Wow, people don't know modems anymore. Yup, I've never had to deal with them much either. Umsm(4) are commonly pre-configured. If you are using a provider provided umsm(4) ATD may be the only Hayes you need.
