Why would there be no flow control available?
Flow control is part of the protocol, no different from escape sequence
parsing. If a terminal emulation receives a control/S from the host, it should
stop sending characters to the host. For that to be meaningful, the "off"
action has to happen close enough to where the characters are picked up by the
driver that you don't get the simulator equivalent of "Fifo overrun" but that
is not hard to arrange.
If the emulation currently doesn't do this, forcing the character rate down to
"really slow" should be an adequate workaround.
