PRI or T1?

You may want to test using ComOS 3.5b8

Also make sure you disable the fallback mode I believe on the Sportster...
it may do speedshifts rather locking in the rate...

now is this possible?

I can hardly wait until the code is perfected and I'll see 50% 28.8 and
49% 33.6 and 1% junk... erm... ;)

Overall, it's been working! some little tweaking on the users end...but
still waiting to see one absolute, cannot work situation...*sigh* I know
there are a couple of V.Fast or V.FCs out there...
