+Vishay TOIM4232
+-------------------------------------------------------------------------------
+
+This is a set of example captures of the initialization and communication
+of a Vishay TOIM4232 "SIR Endec for IrDA" chip.
+
+This chip is usually connected to a TDFU4101 (or similar) infrared transceiver
+module (SIR).
+
+In this setup, a microcontroller initializes the TOIM4232 (which defaults
+to a baud rate of 9600 on its UART, pins TD_232 and RD_232), then changes
+the baud rate to 57600, and finally sends out ten bytes at 57600 (0x11,
+0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88, 0x99, 0xaa).
+
+The receiver side (another device) is also probed ("Receiver RX" pin).
