Well, it depends on what modem you have. To use it under minix, you
should have a standard modem eg. it should have UART (serial port chip)
nad accept Hayes AT commands. If it's an ISA modem it should work with
no problems (just determine IO port number and IRQ). If it's one of
those "softmodems", there's no chance of getting it to work unless
you're going to write your own drivers
