Since forever this driver has had IXON and IXOFF mixed up, and has used the latter rather than the former to enable hardware-assisted software flow control on output.
Ugh, that's a huge sign that no one actually uses IXON/IXOFF anymore :(
Could be that some applications set both IXON and IXOFF "just to be safe"; that appears to be the case with minicom at least.

Anyway, thanks for fixing this up, should also probably be backported to the stable kernels.
I considered that, but since its a change in behaviour I figured it was best that anyone affected hits this with a major (minor?) kernel version update (rather than a stable update). But I'll add a stable tag if you think it's warranted?
