2-way calling on voice line

[Joseph E Poplawski]

Hello.  I am currently running ISC UNIX V.3 on an 80386 with a Hayes Smartmodem
1200.  The only phone line I have at this time is my voice line.  What I would
like to do is have my system be able to receive calls at certain times/days.
But I also need the system to be able to call out when it has to do its polling
for news and mail. The modem is connected to tty01.

Any help and information the resident UNIX communication GURU's could give me 
would be greatly appreciated. 

Thanks in advance..

-Jo
