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.

Hardware

Typically, the TS-Modem comes with a 33Kbaud modem, though it can be purchased with the optional feature of a 56Kbaud 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. The TS-Modem can also be purchased with the optional on-board speaker, which is useful during development to monitor call progress. The modem speaker can be turned off by removing a jumper.

Software

The modem can be used with any operating system, such as Linux or DOS. Any typical modem program can be used. In Linux, for example, minicom works quite well. Be sure to use setserial for setting which IRQ minicom and Linux should use.

The modem uses AT-style commands. All commands start with an "AT" when in command mode, and when in data mode, start with "+++". For example, to dial out, the command "ATDT (phone number)" is used. To hang up after the modem has connected, use the command "+++ATH".
