Ver 0.92 (12-18-02) ------------------- * Fixed a problem in the Elm32x scantool detection routine. * Fixed a problem in the GamePad Pro detection routine. * Fixed a timing bug which was causing erroneous "Timeout while waiting for response from the Elm32x device." errors * Gamepad Pro detection is now disabled by default. Use the /GPP command switch to enable it, if needed. Ver 0.93 (06-04-03) ------------------- * Fixed some serious problems in the error handling/reporting routines. * Fixed a bug which may cause scancodes to be read improperly. * Improved "debug mode".

Ver 0.95 (07-06-03) ------------------- * Bugfix: Elm32x chip detection failed, in previous versions, when using an ELM32x V2.0 chip, with echo enabled. Ver 0.96 (01-03-04) ------------------- * Bugfix: Minor display bug when using an LCD character display connected to COM2 ---------- Disclaimer ---------- The author is not responible for any problems that arise from using this beta software.

The default is COM1. /LCD Show data on a Matrix Orbital 2041 Display. Default: PC monitor The LCD display is assigned to the first unused COM port. /LCDBAUD=b Specifies the transmission rate to the optional optional LCD display, in bits per second. The following are valid values for b: 1200 *1200 baud 2400 *2400 baud 9600 *9600 baud 19200 *19200 baud (default) /GPP Enable input from Gravis Gamepad Pro joystick /DEBUG Logs data received from the Elm32x device to "obd.log".
