[comp.sys.apple] Programming modem to answer?

2QN3GLOP@UKANVAX.BITNET.UUCP (05/20/87)

I have a Apple //c computer with a Apple 1200 baud modem.  I downloaded
a small Bulltein Board program from another computer called Mini-Board 1.0.
But I don't know how to program the modem to wait for a call???????
The program looks like this:
        12 DIM N$(50),P$(50),FM(50),TM(50),MS$(50),T$(50,5)
        14 DIM ML(50),MC(50)
        20 PRINT : PRINT "******Mini-Board 1.0 ******"
        30 PRINT "Waiting for caller." :REM
        32 REM for your specific computer
        37 XX = 0
        40 PRINT "Incoming call." : PRINT
        42 FOR I = 1 TO 500: NEXT I: REM
        44 PRINT "Welcome to the Mini-Board."
        etc......

I tried putting in 32 PRINT "IN#2" (with a ctrl-D after the first quote),
but it ignored it.  What am I missing in order for the modem to wait for
the call, answer the call and then proceed to line 44.  Thanks in advance.
