This discussion has generalized beyond PPP/LCP now -- this information is generally useful to anyone supporting dial-in connections, and especially those sharing modems and lines for in and out.

This is good, but if your modem supports something like the "Q2" command in which results are supressed (quiet mode) only in answer mode, this is even better. Then you don't have to issue the "ATQ0" in the dial string or init string to dial out, nor guarrantee that the modem was fully reset on each transition (though doing a reset on the DTR transition is usually a win, anyway). I don't know how many modems support this, but US Robotics Couriers and Sportsters do, and they are quite popular. If your modem doesn't support Q2 or something similar, then Joe's suggestion is the way to go. > No modem I have ever seen works out of the box correctly with a UNIX host > for both in- and outdial applications.
