Details:
When trying to use a non-standard BAUD rate (195313 in my case), avrdude
comes up with this and then stops;
avrdude: serial_baud_lookup(): unknown baud rate: 195313
After patching the source to bypass that error and just return the rate, it
turns out that arbitrary BAUD rates work fine with my setup and programmer and
there seems to be no need for this to fail.
Joerg Wunsch pointed out that arbitrary rates may not work with every driver.
The attached patch makes it so that avrdude first searches the default BAUD
rates and returns the associated constants. If it is not a default rate, then
it issues a warning and returns the non-standard rate.
I've compiled and tested this on Windows and it works. I've compiled it on
Linux (which works), but cannot test it there.
