If you put in ten commas (as you mention), you're going to be pausing so long that the operator will have come on the line after the bong tone, and s/he won't appreciate getting blasted with your credit card number! If you use commas, you will have to tinker with it at each hotel to get the number of commas right, so that the credit card number starts to dial within about five seconds after the bong in order to avoid getting the operator. What I do instead is use the "@" dial modifier, e.g.: ATDT 8W0XXXYYYZZZZ@AAABBBCCCCDDDD The "@" (Wait for Quiet Answer) dial modifier is supported in most modems today. It causes the modem to pause, listening for some sound in the call progress signalling band, followed by five seconds of silence, and then continue (five seconds are required to differentiate a "quiet answer", used in some direct inward system access features, from the normal four-second pause between ringback tones). The BONG tone triggers it in most modems, because the last part of the BONG is a decaying dial tone (which falls in the call progress band). Sometimes the five seconds is too long and the operator comes on the line, but usually just trying again works OK. If it turns out that the operator ALWAYS comes on the line before five seconds of silence has expired, you don't have much choice but to revert to a series of commas (and tinker until you get them right, and hope that the time it takes the hotel PBX to send you to AT&T is fairly consistent). You could, of course, always use ONE comma, and then use the S8 register to set its length. This may make it somewhat easier to "tinker", without having to edit the phone number. FYI, I'm calling into our Vax in Atlanta right now, charging the call to my corporate AT&T Calling Card, having used the method described above. Works great. Only blasted the operator one time so far this trip! Toby Nixon, Principal Engineer | Voice +1-404-840-9200 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.
