Or RF amongst other media for that matter.
This can be an important issue at times. A completely transparent INT driven
media transaction can be ruined by having to "poll" for the last stop bit
having
been shifted out before you turn off the media ....
(That H8/Tiny must have been fun and games on RS485, collison galore !)

Personally I dislike vectors that share Rx and TX -  still, could
be worse, you could be on a PIC with 1 ISR only :-)
