Some peeks/pokes regarding modems, from zimmers.net:

Detecting a ring:
if(peek(56577) and = 0  then print "ringing"

Detecting a connection is accomplished by simply watching the Data  
Carrier Detect line on the modem port.  That will be bit 4 in location  
56577.  When the following BASIC condition becomes true, the BBS should  
go online:  

   (peek(56577)and16)=16  
 
The BBS program should go online by swinging its Data Terminal Ready  
signal high.  This can be done with the following:  
poke56577,6:poke56579,6  
 
The BBS program should hang up whenever it detects the Data Carrier  
Detect line go low.  That's done with something similar to the peek  
above:  

   (peek(56577)and16)=0  
 
The next step is to drop the Data Terminal ready signal by entering:  

   poke56577,0:poke56579,32
