PowerBook Modem Fix?

by Adam C. Engst

PowerBook Modem Fix? -- Jonathan Feinstein of Shrink2Fit Software passes along a useful hint for people having problems connecting to remote modems from their PowerBook's internal Apple modem. Apparently, these difficulties come from some non-standard aspects of Apple's error correction firmware routines, which Apple wrote that way to avoid infringing on Hayes's modem patents. This is not related to the problem we reported on earlier with the PowerBooks losing input data at high speeds.

Jonathan says that Apple tech support suggested that he replace the standard "ATDT" dialing command with "AT&Q0DT" (that's a zero, not a capital letter O, after the Q). In other words, the command to dial Memory Alpha BBS would be "AT&Q0DT 1-607/257-5822" instead of "ATDT 1-607/257-5822". Note that many programs dial automatically, so you may need to reconfigure your program's default dialing command.
