Your modem has this info built into it. Open up a terminal program, such as minicom, that is configured to use your modem device and enter the folloowing AT commands. at$ - list commands at&$ - list & commands atd$ - list dial commands ats$ - list S registers [ note from the LTT maintainer : the author also sent me the following email : Someone replied to my post saying that it did not work on their modem. I got this tip from somewhere, maybe usenet, I can't remember. So you might want to put a YMMV disclaimer with it. Basically if it works great, no need to dig out the manual, if doesn't...RTFM. ]
