Autobaud Modems

[Henry Spencer]

Actually, this scheme (use a spare modem-control line to sense the modem's
baud-rate indication, have the driver set the speed codes based on this,
and have getty do an ioctl to find out) is found in vanilla V7.  One
difference:  V7 uses the secondary-receive line rather than ring-indicator.
