- i already answered this question it changes the rate from what you type
- to 19200 then to 9600 then to 19200 to do something to do with anti snooping
- or sdl authentication then it changes the rate again to what you specify
- to transmit the actual code..
-
- its something like this
- sdl at 115200k
- switch to 19200
- transmit 1 character
- switch to 9600
- wait for character to be sent back
- switch to 11200 xmit modem code
-
- (this doesnt include of course the country checking..)

- ive done about what 5 firmware loads so far? from 1994/95 to now.
- you dont hafto worry about that floating dte rate.. just dont run
- the flash process in a dos window.. reboot to dos then run it then
- go back to os/2 or windows or whatever

-
- thats probably because theres something about reading what i said that
- must be too hard for you.
