IIRC (long time since I plumbed layer 0 :)) Xoff & Xon (sometimes
generated from the keyboard by ^S and ^Q) tell the other end of the link
to stop & restart (respectively) transmission. Inward & outward flow
control is acheived by sending Xoff & Xon chars in each direction: the
characters used are the same in each direction. (You could also have
Xoff/Xon aka software flow control in one direction and hardware, or no,
flow control in the other: the two directions of data flow are
effectively independent channels.)
