stty -a < /dev/ttyS1 shows clocal.
Dialout a pppd link on ttyS1.
stty -a < /dev/ttyS1 shows -clocal.
Turn the external modem off, pppd dies.
Turn modem back on, try to dial out again.
stty -a < /dev/ttyS1 now hangs in open, as does any other attempt to
open ttyS1.
stty -a < /dev/cua1 still shows -clocal.
stty clocal < /dev/cua1 fixes the problem.
Of course cua1 is depreciated :(.
The problem of -clocal remaining also seems to occur if the other end
of the link drops the connection.
