Palm Dot Commands

The followings are so-called dot commands of PalmOS. The dot commands are the combination of the shortcut character (like lower case 'L' in handwriting) and '.' (period, double tap) and number or alphabet in Graffiti.

WARNING: These commands are unpublished and unsupported functions. And include very dangerous commands for normal users. I won't take any responsibility for any damages caused directly or indirectly by the use of these commands. Use these at your own risk.

I found the official description for developers. (2002-02-20)

1. Puts the device into the debugging mode. It's for the developers use. To get out of this mode do soft-reset.
2. Puts the device into the console mode, another debugging mode.
3. Stop the auto switch-off function. After entering this command the device will not switch-off automatically. Soft-reset to re-enable auto switch-off.
4. Show HotSync user name and user-id briefly. HotSync user name is the name apears on the upper right corner of the HotSync application. It is used by PalmDesktop too.
5. Erase the log of HotSync and HotSync user name and user-id. If you issue this command, the history of HotSync is deleted. So next time you hotsync, the data of DateBook etc. will transfer again and all entries are dupulicated. Use this with caution.
6. Show the date when the ROM image is created (not burned).
7. Change the battery profile. Changing the profile affect the voltage at which the warning dialog appears and at which the device won't switch on, the formula for the voltage gauge etc. Repeating this command over and over will cycle through all the available profiles of the device.
8. Inverse the display of the backlight. On some devices, ex. Visor Deluxe, you can enter the command and see the feedback, but nothing will change.
i. Enable the IR receiving. You can receive data via IR even if you switch off the beam receive in Preference. You can memorize this command by the phrase like, 'i' is the first letter of infra red.
s. Redirect the data flowing through infra red port to serial port. Enter again or soft reset to return to original mode.
t. Put the infra red port into the loopback mode. The data sent through infra red port will be received on the infra red port of the same device. You can beam the entry of DateBook etc. to the same device with this mode.
