I can understand | that happening if maybe I am running a communications program, | but the crazy modem does it when in BASIC mode or running a game. Every 1670 model modem I have ever used has been the same. It suffers from being too sensitive, and a host of other problems. The best thing to do is everytime you turn on your computer send this basic command: open2,2,0,chr$(6),"ats0=0":close2 This is the correct open statement, but feel free to correct me if I am wrong. This is generally the best way to turn off the answering mechanism of the modem, save unplugging the modem, or disconnecting the line from it. The 1670 isn't really "Hayes compatible" per se. It suffers too many problems and has too many bugs to be considered such. It only has about half the command set; commands have to be in upper case (at least on all the modems I have seen); it's too sensitive; and generally has a terrible speaker. Considering everything, it's a great idea to just buy a Hayes modem itself, and then buy a $40 interface. All in all, it solves alot of problems. -- Chad Gibbons | System addresses: 1750 N.
