Definition of line sharing (In case you need it): Line sharing is a way to  
use a phone line for data and voice calls, without the two interfering with
each other.
  

  Do you run a BBS only part time, because you cant afford a new line? That's
my case too. Well I was thinking about some way to enable voice/data line
sharing with my board so I could go 24 hours, and I remembered this handy dandy
little option that GTE offers. With their Smart Ring option, your phone line
has two phone numbers, and each of them rings differently. One line rings
normal, Ring....Ring.....Ring....., and the other line does double rings,
Ring-Ring....Ring-Ring....Ring-Ring....(I know, you never would have uderstood
if it weren't for my awesome text interpretation of the rings..) Anyway, I
figure if the BBS can decipher the rings, and only pick up on one type, it
would be a great way to line-share. So enough with the explanation, on with
the mod.


DISCLAIMER: If this mod causes your computer to start programming you, I'm not
            responsible!


STEP ONE: Duh! What's every mod's first step? Say it with me now, BACK UP YOUR
          SOURCE CODE!!! And a nifty way of getting that done is to type:
               PKZIP SOURCE *.C *.H
          in the directory your source code is in.


STEP TWO: Load bbs.c. Now because I'm a nice guy, I'm going to include both
          mod methods. The one to make Smart Ring be your voice line AND the
          one to make regular ring be your voice line. In my case, I wanted
          the voice line to be the one with Smart Ring, but the code for the
          opposite was a lot easier, and thusly I found it first. Now I had
          to do so much jumbling of stuff in this little section of code, so
          I'm just going to have you delete code and replace it. This part
          applies for both methods. Find void getuser() and remove this chunk
          of code:
        
        
        outs("* ");
        if (mode_switch(1.0,0)==mode_ring)
          answer_phone();
        else if (modem_mode == mode_con) {
          incom=outcom=1;
          if (!(modem_flag & flag_ec))
            wait1(45);
          else
            wait1(2);
        }
      }
    }
        

METHOD ONE - Smart Ring as VOICE line: Replace that code with this:
        
        outs("* ");
        if (mode_switch(1.0,0)==mode_ring) {
          if (mode_switch(2.0,0)==mode_ring) {
            outs("\x0c");
            outs("Voice call detected. Suspending program for 60 seconds.");
            sleep(60);
            incom=outcom=1;
            if (!(modem_flag & flag_ec))
              wait1(45);
            else
              wait1(2);
          } else
            answer_phone();
        }
      }
    }


METHOD TWO - Regular ring as VOICE line: Replace the code with this:

        
        outs("* ");
        if (mode_switch(1.0,0)==mode_ring)
          if (mode_switch(2.0,0)==mode_ring)
            answer_phone();
          else {
            outs("\x0c");
            outs("Voice call detected. Suspending program for 60 seconds.");
            sleep(60);
            outs("\x0c");
            incom=outcom=1;
            if (!(modem_flag & flag_ec))
              wait1(45);
            else
              wait1(2);
          }  
      }
    }


STEP THREE: That's it! Just save bbs.c and recompile. Was that painless or
            what? You now have a fully-functional voice/data linesharing
            BBS. Hope you enjoy it!
