You're out of luck-- get out the checkbook, the urge is back.

     Modem settings:  B0, &B1, &H1/&H2/&H3,
        &M4/&M5, &N0

      Dual Standard modems always connect with
      each other, either in HST mode or in
      V.32 bis mode.  However, we  recommend
      that Dual Standard modems be set to B0
      and to &N0, so that they can connect
      with V.32 bis, HST and lower-speed
      modems, in both Originate and Answer
      modes.

(both from the USR manual)
Basically, lock your dte rate at 19200 or 38400, set modem to &B1 (Fixed
DTE rate) and B0 (V.32/V.32 bis mode).
Dual Standards connect to each other according to the mode of the ORIGINATING
modem.  HST modems will cause an answering Dual Standard in V.32/V.32bis
mode to switch to HST mode.
