Basically yes, but it can do more than that. > i just want to > config my modem by AT command. This is _exactly_ what PPP does (among other things). :-) Refer to the example I've provided in an earlier message on how you can use /etc/ppp/ppp.conf to define the settings for speed and flow control which will then be processed by PPP, it will send the _proper_ AT commands using chat (see "man chat" for details). On the other hand, if you use a program like minicom, there will be a config file provided where you can put your settings and custom AT commands (if required) into it. I haven't been using it for long time, but if I remember correctly, the config file is /usr/local/etc/minirc.something... ??? > when my ppp.conf file is empty, i can talk to my modem so this config file > do nothing what you want talk to your modem. The file is only relevant to PPP. If you're using a different program, it will be ignored. Only PPP reads it at startup. > if i want to talk to my modem by a specific speed, which config file should > be changed? That depends on the _program_ you use to talk to the modem. Again: If you use ppp, put "set speed 115200" (or whatever speed you need) in ppp.conf's section for your connection. If you are using a different program, check its documentation to find out which config file it uses. There is no system-wide configuration file for what you need. -- Polytropon 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"
