Shortcuts are handy little things built in to the PalmOS to make life a little easier. You can define a shortcut by going to the "Prefs" application and choosing ShortCuts from the pull down list. Then when you are writing something in Memo Pad or some other application that allows Graffiti input, use the shortcut symbol (pictured at the right) followed by your shortcut. For example, one of the defaults is "dts". Write the shortcut symbol followed by dts and the OS will replace it with a date and time stamp.
Shortcuts are well documented, dot commands are not. Dot commands are a type of shortcut that allow you to do some helpful (and occasionally destructive) things to your PalmOS device. So please take this word of warning. Some of these dot commands could cause you to lose data or force you to do a hard reset. If you use any of these commands, you do so at your own risk.
To use any of these dot commands, open up Memo Pad, write the shortcut symbol (see above) followed by two dots (to make a period) and then one of the numbers or letters below. These commands should work on all versions of PalmOS. This information was mostly taken from David Brooke's excellent Undocumented Palm Info v2.
| Command | Result |
|---|---|
| 1 | Enter debug mode and halt the application currently running. Debug mode is useful when programming your PalmOS device. One warning: debug mode keeps your serial or USB port open so it will rapidly drain your batteries. |
| 2 | Puts the device into the console mode. ( Same as 1, except that the application keeps running?) |
| 3 | Disable auto power-off. After entering this command the device will not switch-off automatically. Soft-reset to re-enable auto switch-off. |
| 4 | Briefly displays the user name and unique ID of that device. This information is used to identify your handheld when hotsyncing. |
| 5 | Erases the user configuration and clears the hotsync log but doesn't clear your data. WARNING! If you attempt to hotsync after this, it will download all your information as duplicates. Do a hard reset to avoid that. I have no idea why you'd ever want to use this dot command. |
| 6 | Displays the ROM revision date. My Visor says 1/25/00, 1:35 pm |
| 7 | Toggles the battery mode. Depending on your PalmOS revision, it will cycle between Alkaline, NiCad, Rechargeable Alkaline, and NiMH.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 | Toggles IR beam receiving on and off. When on you can receive data via IR even if you switch off the beam receive in Preference. |
| 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. |
| x,t,s | Brooke notes that these three exist, but the only thing they seem to do is force him to do a hard reset. In other words, don't use them. |
The most useful dot commands are 1 and 7. 1 is helpful for programming and 7 is useful so that the Palm can more accurately warn you when you will need to change your batteries. Dot commands are handy things, but as noted, some of them can cause a loss of data. Be careful what you write!
