From: Jan Dumon <j.dumon@xxxxxxxxxx>
Don't send flow control settings to any port other than the modem port.
Older firmware ignored this request but did sent a reply. Newer firmware just
ignores it without reply and causes a 5 second timeout every time a port
(except for the modem port) is opened or if tiocm settings are changed.
