- You misunderstood my question. I am well aware of the LOGICAL and
- REASONABLE reason for the ability to set different rates for the SDL utility.
- My question, put another way, is:
-
- Why bother with that option if the SDL utility will control the rate and
- change it as it sees fit?

- Well, I agree somewhat with the remarks about USR's uitility limiting it
- to DOS. However, until the later issues, the Supra did the same thing. My
- ZyXel (U-1496E) required that I find someone to burn a prom for me.
-
- I don't think USR's doing anything less than anyone else except dragging
- their feet about porting the loader to other platforms. I don't know that
- it does change the DTE rate during the upgrade process, by the way,
- that's a claim that's been made by someone else. I am questioning his
- original remark that someone should allow the rate to "float" in order
- for the loader to work and that isn't true.
