I need some advice on the use of a Practical Peripherals 2400SA modem
hooked to a UNIX computer running Sys5.2.  

As shipped, the Data Carrier Detect is forced on.  If a caller hangs up
without logging out the line is not dropped and the port seems to be
effectively hung until I kill the uugetty running on it.

On the other hand, if I set DCD to track the state of the remote
carrier the computer won't talk to the modem.

What am I doing wrong? Ideas appreciated. Please respond by Email.
Many thanks.
