Anyway good modems are able to perform the equivalent of ATZ at a DTR drop. I've seen it at least on a Hayes Optima. Note that every close of the device causes a DTR drop under Unix, so this is indeed a nice way to reset the modem to its defaults. As Ollivier also remarked, decent modems don't pick up the phone line if they miss DTR. Alas, alot of modems are broken in this field. > (WEll, something that has the same effect as /etc/default/uu*S? in gettyps) > ? I suppose I could, but what is the proper tool to do this? Kermit or > chat from pppd-2.1.2c package? chat might be worth a try, i think it's fairly easy (but misses a man page). Btw., it's in the system by default, you don't need a package for it. Kermit in connection with some script might also do it. > Hmm, I tried mgetty under linux but I still can't get into one thing: > is there any way to use this stuff in the system with zoo of modems > of different type, init strings are hardwired, right? Sorry, i don't have an idea. I'm using mgetty only as a workaround for my broken modem, and as soon as i've got a better modem, be sure: i will go back to the regular getty.
