- It's a more conventional design, with firmware in EPROM. The internal
- version uses a buffered 16550 UART (which is as good as Intel's UART
- emulation for most purposes). It works in data mode with virtually
- any computer, operating system and comm software. The fax is Class 1,
- whereas Intel uses CAS -- most (but not all) good software supports
- both "standards". (Now that Class 2 is finally approved, I expect USR
- to migrate the Sportster to Class 2.) The hardware in the USR is
- proprietary, based on USR's long and extensive expertise in modem
- design, and therefore is very solid.

- Not really, because all it does for data mode is download the firmware
- during boot up.

- My biggest complaint about Intel (other than the DOS-only device
- driver) is that it has problems connecting to certain older (2400bps
- and down) modems, problems that the USR does not have. Also, I found
- that the USR gets slightly better data throughput, especially on
- marginal lines. Finally, I found quite a number of minor glitches
- (aka bugs, like it doesn't work on certain phone lines, and is not
- fully compatible with DESQview), and my experience with Intel made me
- doubt that they would get fixed.
-
- The one significant potential advantage of the Intel 400 is that it
- features automatic fax/data sensing, so you can have both data and fax
- software waiting for incoming calls at the same time. The USR can do
- one or the other, but not both at the same time.
-
- Intel claims to support 14400bps fax, whereas USR is "only" 9600bps,
- but the feature is of little value as you're unlikely to find a remote
- system that supports more than 9600bps (and the 14400bps speed was
- broken in the original release of the 400). Intel also claims better
- fax compression than USR, but I did not observe any significant
- difference during my testing.
-
- The bottom line, at least for me, is that Intel has an innovative
- concept that is marred by implementation flaws, whereas USR has a more
- conventional design that's solid as a rock.

-
- I'm also not a fan of Intel's "FAXability" software. Far better,
- IMHO, is Delrina's recently announced WinFax PRO >> 3.0 <<, which I
- have been beta testing -- highly recommended!
