I am using a Racal-Vadic VA212 modem for both dial-in and dial-out access.
One curious thing about the terminal driver on UNIX is that in order for
the open call on a tty to complete, the CXR line must be on (that is there
must be a carrier on the modem line). However, this cannot happen until
the modem can be told to dial out and establish contact with a remote
system. Is there any easy way to fix either the tty driver or open call
so that it doesn't wait for CXR?
