There are several ways to do this with varying degrees of ease and cost. The most common (if youre only using two modems) is to hook one to the printer port and one to the modem port. Make two nodes within your bbs host software. One that sends commands to the printer port and one that sends commands to the modem port. Its as easy as that. Depending on which number people dial they will end up on either the modem or printer port. I used to use this method back when i ran  TeleFinder BBS. Best of all its dirt cheap. If you need to be able to use MORE than 2 modems the most popular method is to buy a hurdler card. It lets you add more serial ports  to which you then connect more modems. Then you follow the same steps as before and add nodes within your BBS host software and assign them to the different ports. Ive seen this run effectively on a MacII. I cant imagine youd want to use anything less than that but you could if you really had to. To squeeze the best performance out of it suggest at least a 6100/66. Great little workhorse machines that, while theyre not the fastest, get the job done with PPC optimized speed. If youve got something better than that by all means use it. It also depends a little on how many modems you plan to hook up. If you want to hook 20 modems up to it id suggest putting two or more macs on a network and splitting the modem load. There are various tricks to getting the BBS software to notice its counterparts on different computers but i wont go into those all now because you could probably write a book on it. If you get to that point and need some tips just ask and ill give ya all the info you need and probably some ya dont need.

Whoopse...forgot to mention another alternative. If you have 2 or more macs already (lets use 2 macs for examples sake) you could network the two and put two modems on each computer thus getting 4 modems. Obviously the network would have to be ethernet 1) because of speed and 2)because appletalk would take up a serial port that you want for a modem. That would cut your costs to ethernet cable and depending on your cabling, a hub.
