IBM LPFK reverse engineering

IBM LPFK 6094-020 victims .. It's been a year, but I finally found what I was looking for. Which is good because I was about to go mideval on an AIX 4.3 box to get the data that I needed. ;-) Somebody deep inside the Blue Wall had the docs on a CD-ROM. Here is the quick summary: Protocol: 9600,O,8,1 with no handshaking Commands (shown in hex) 0x01: Reset: Similar to the power on reset. Leaves the LPFK in the 'disabled' state with all indicators off. 0x06: Read configuration: Upon getting this byte the LPFK responds with 0x03. Helpful for determining if the LPFK is active on a serial port. 0x08: Enable: Tells the LPFK that it may process and send keystroke data to the host machine. 0x09: Disable: Keyboard input is disabled. The LPFK will still respond to Reset and Read Configuration 0x94: Set Indicators: This command is followed by four more bytes which is a bitmap that represents the indicator lights on the keys. If the bit for a key is turned on, the light will be turned on. If the bit for a key is 0, the light will be turned off. Keys are numbered from 0 to 31. Responses from the LPFK: 0x00 to 0x1F: Keystroke: The corresponding key on the LPFK was hit. These responses are only sent when the LPFK has been enabled using the Enable command. 0x80: Retransmit: The LPFK sends this if there was an error on the last Set Indicators command and it wants the host machine to retransmit it. 0x81: OK: The LPFK sends this if the last Set Indicators command was received successfully. All of this is also written up at http://brutman.com/IBM_LPFK/IBM_LPFK.html for the good of the greater public. Now I need to figure out how to run 9600 bps on a PCjr .. it doesn't like anything over 2400. (4800 or 9600 might be ok, as it just is one byte being received.) Mike
