+
+/*
+ * This driver has currently only been tested on the IRWave IR320ST-2
+ *
+ * PROTOCOL:
+ *
+ * The protocol for talking to the TOIM3232 is quite easy, and is
+ * designed to interface with RS232 with only level convertors. The
+ * BR/~D line on the chip is brought high to signal 'command mode',
+ * where a command byte is sent to select the baudrate of the RS232
+ * interface and the pulse length of the IRDA output. When BR/~D
+ * is brought low, the dongle then changes to the selected baudrate,
+ * and the RS232 interface is used for data until BR/~D is brought
+ * high again. The initial speed for the TOIMx323 after RESET is
+ * 9600 baud. The baudrate for command-mode is the last selected
+ * baud-rate, or 9600 after a RESET.
+ *
+ * The dongle I have (below) adds some extra hardware on the front end,
+ * but this is mostly directed towards pariasitic power from the RS232
+ * line rather than changing very much about how to communicate with
+ * the TOIM3232.
+ *
+ * The protocol to talk to the TOIM4232 chipset seems to be almost
+ * identical to the TOIM3232 (and the 4232 datasheet is more detailed)
+ * so this code will probably work on that as well, although I haven't
+ * tested it on that hardware.
+ *
+ * Target dongle variations that might be common:
+ *
+ * DTR and RTS function:
+ * The data sheet for the 4232 has a sample implementation that hooks the
+ * DTR and RTS lines to the RESET and BaudRate/~Data lines of the
+ * chip (through line-converters). Given both DTR and RTS would have to
+ * be held low in normal operation, and the TOIMx232 requires +5V to
+ * signal ground, most dongle designers would almost certainly choose
+ * an implementation that kept at least one of DTR or RTS high in
+ * normal operation to provide power to the dongle, but will likely
+ * vary between designs.
+ *
+ * User specified command bits:
+ * There are two user-controllable output lines from the TOIMx232 that
+ * can be set low or high by setting the appropriate bits in the
+ * high-nibble of the command byte (when setting speed and pulse length).
+ * These might be used to switch on and off added hardware or extra
+ * dongle features.
+ *
+ *
+ * Target hardware: IRWave IR320ST-2
+ *
+ * The IRWave IR320ST-2 is a simple dongle based on the Vishay/Temic
+ * TOIM3232 SIR Endec and the Vishay/Temic TFDS4500 SIR IRDA transciever.
+ * It uses a hex inverter and some discrete components to buffer and
+ * line convert the RS232 down to 5V.
+ *
+ * The dongle is powered through a voltage regulator, fed by a large
+ * capacitor. To switch the dongle on, DTR is brought high to charge
+ * the capacitor and drive the voltage regulator. DTR isn't associated
+ * with any control lines on the TOIM3232. Parisitic power is also taken
+ * from the RTS, TD and RD lines when brought high, but through resistors.
+ * When DTR is low, the circuit might lose power even with RTS high.
+ *
+ * RTS is inverted and attached to the BR/~D input pin. When RTS
+ * is high, BR/~D is low, and the TOIM3232 is in the normal 'data' mode.
+ * RTS is brought low, BR/~D is high, and the TOIM3232 is in 'command
+ * mode'.
+ *
+ * For some unknown reason, the RESET line isn't actually connected
+ * to anything. This means to reset the dongle to get it to a known
+ * state (9600 baud) you must drop DTR and RTS low, wait for the power
+ * capacitor to discharge, and then bring DTR (and RTS for data mode)
+ * high again, and wait for the capacitor to charge, the power supply
+ * to stabilise, and the oscillator clock to stabilise.
+ *
+ * Fortunately, if the current baudrate is known, the chipset can
+ * easily change speed by entering command mode without having to
+ * reset the dongle first.
+ *
+ * Major Components:
+ *
+ * - Vishay/Temic TOIM3232 SIR Endec to change RS232 pulse timings
+ * to IRDA pulse timings
+ * - 3.6864MHz crystal to drive TOIM3232 clock oscillator
+ * - DM74lS04M Inverting Hex line buffer for RS232 input buffering
+ * and level conversion
+ * - PJ2951AC 150mA voltage regulator
+ * - Vishay/Temic TFDS4500 SIR IRDA front-end transceiver
