As I mentioned on the previous page, to get the timeout correct:
https://bitcointalk.org/index.php?topic=179769.msg2921457#msg2921457When you switch the frequency via the API it recalculates the timeout for you.
(so if you just set the frequency the same as it currently is, it will correct the timeout)
But it also shows you on the screen (and it's in the API stats)
If you have 1 board 2x10 then the options are 115200:2:10...
If you have two boards chained together with 4x10 then the options are 115200:4:10...
etc.
