The TS-MODEM2 is a PC/104 (standard format) peripheral board with a Modem socket that supports all the MultiTech modems and a jumper selectable 3.3V or 5V power supply.

The TS-MODEM2 supports all MultiTech "Socket Modems" including:

• GSM cellular modems
• CDMA cellular modems
• Land-line modems
• Bluetooth® module

In addition, the TS-MODEM2 features a 16550 serial UART with 16-byte FIFO at the COM port used to communicate with a MultiTech socket-modem and optional battery-backed real-time clock. UARTs, I/O locations (COM4 or COM6), and Interrupt Lines (IRQ5, IRQ6 or IRQ7) are jumper configurable.

The RJ11 connector (phone jack) is required for the MultiTech Land Line modem; however, the user must remove it for other modems, such as the cellular module. The battery-backed RTC option is for use with TS-7200 and TS-5600 products only.

The TS-MODEM2 uses a standard 16C550 UART; therefore, any device driver for this chip will work. For example, the TS-Linux distribution already includes Linux drivers for the 16C550 UART chip by default. One can use any terminal emulator, such as minicom, to open and configure the serial port in use by this board with the appropriate /dev entry, enabling communication to the modem device plugged into the socket.
