Please help, I've exhausted the USRobotics site and found no upgrade path.

The Askey modem cross-references to J-Mark and Phoebe brands (presumed cross-badging of nearly identical units). Askey and Phoebe don't provide an apparent mechanism for reflashing.

J-Mark supplies accessible downloads for this model: 56K V/D/F Rev 10.3.35 (firmware HCP-02 USA 9706160), but the flash software fails to install the updated firmware.

Any help is welcome and thanks in advance,

Thanks for the link to USR's archives, not at all obvious as to how to access it from their website. I found the appropriate model#-up.exe, downloaded it and attempted to flash using Win98SE's bundled driver for control interfacing. That bounced, so I had to experiment by loading one of the drivers provided by USRobotics compressed in mdmusr.exe.

One driver, Sportster 56000 Voice Internal, permitted model#-up.exe to flash the ROM and the device now reports V.90 with the new flash and DSP rev's as 4.9.1, up from 4.1.11.

Now for the other frustrating ISA hardware modem, V1456VQH-X. It has a TI chipset, one that your site identifies as typically USR or 3COM (TMS320X), but the FCC#: H8NTAI-31778-M5-E suggests otherwise- Askey, J-Mark or Phoebe as found at Rob Clark's modem/winmodem site, http://start.at/modem.

I'll continue digging, but attempts to use J-Mark's updating scheme failed. Perhaps I ought to experiment with different device drivers to see if it permits the flash program to rewrite? Unfortunately, Askey, J-Mark, and Phoebe all refer to 96-C807241.zip for its primary drivers.

This will require more work.
