According to this manual:
Slow/Search (or rewind fastforward) would be
!7SCNds where
? d is either F or R?
? s is f or s
And this cycles between 6 different speeds for fast and slow.
An SIO for
fast_forward (forward fast)=? !7SCNFf\x0D
rewind (reverse fast) = !7SCNRf\x0D
slow_play (forward slow) = !7SCNFs\x0D
it would seem however that Reverse Slow is not supported?
slow_rew (reverse slow) = !7SCNRs\x0D
Next Track = !7SKPNX\x0D
Prev Track = !7SKPPV\x0D
