The TS-Modem is an add-on PC/104 modem daughter board. It adds one AT-command style compatible Modem that can be directly connected to a dial-up telephone line. The modem interface is a 16C550A compatible UART with 16 byte TX RX FIFOs. The I/O port address and the IRQ used can be set with jumper blocks on the board itself. Typically, the TS Modem comes with a 33K baud modem, though it can be purchased with the optional feature of a 56K baud modem. The TS-Modem can also be purchased with the optional 16-bit PC/104 connector, which is required if using IRQ 10, 11, 12,14, or 15.
