  • Model: 3Com/USR Sportster 56K (All)

        &F1&H1&R2S15=128S25=40
    Occasionally we run into problems where connections are made, but no data is transfered. We have found the S15=128 to remedy this.

    Sometimes these modems "choke" at the 56K negotiation process. In this case, disable V.90 with S32=34

  • Model: Several (See Notes Below)

    We have seen cases where this is the only string that will keep some modems connected. The modems are typically Texas Instruments chipset based (like USR/3Com modems), but are normally not actually made by USR/3Com. This is most often in Packard Bell or NEC computers.

  • Model: Message Modem Model 5668
      Submitted By: Internet User
        AT&F&B1&A3E1Q0V1&C1&D2&P1S0=0
    This was sent in by a user which enables pulse dialing for the Supervoice program that ships with the modem.
