What modems can I use on my Amiga?

You can use any standard PC modem. However, as many PC modems have a 9-pin connector you will need to get an adaptor to plug into the Amigas 25-pin port, or you can add a serial port by using a multiface card or the Surf Squirrel on an A1200. This is the best option as the Amigas internal serial port is verrrry slow with only a one byte buffer. You should be able to use the serial port at a speed of 38, 400 bps (Bits Per Second). This may still cause errors if you only have a 68000 processor. The faster the CPU the faster your modem speed can be. To find out more follow this link.
