Ok, I'll accept that CTS/RTS signaling is a local convention between
the computer and the modem.  Now, tell me this: MNP modems implement
compression and error detection, which suggests that there is a two-way
protocol between two MNP modems independent of the user-level data that
they send to each other.  Does this protocol implement flow control also?
That is, if you drop your ?TS signal to an MNP modem, won't it eventually
inhibit sends from the other modem, and won't that eventually inhibit sends
from the other computer?  (Where the other modem and the other computer have
been set up to do ?TS or ^S^Q flow control.  Just because your end does
?TS doesn't mean the other end does!)
