# 3. Settings

You will get access to settings by using the popup menu of the left view. Please note that settings are automatically saved when you exit TiLP2.

## 3.1 Device

The box is the following:
1°) Cable : let you select a cable from a list
2°) Port : let you choose a port from a list. The correspondance is done below
3°) Calc : let you choose an handheld
4°) Timeout : default timeout in tenth of seconds (1/10 s). This determines how long TiLP will wait for a response before displaying an error message. It is strongly recommended not to decrease the value below 1.5s or you may get transmission errors.
Please note that during FLASH transfers, this value is automatically increased to 10 seconds.
5°) Delay : inter-bit delay for serial/parallel cable in micro-seconds. The lower the value is, the faster the transfer will be. However, the transmission will become unstable (transmissions errors) if you try and go too fast. 10µs is the optimal value. If you have a fast calculator (TI89/92/92+), you can decrease it.
6°) USB scan at startup: attempt to automatically find FLASH handhelds plugged on SilverLink or DirectLink at startup. If OS sending failed and you need to restart TiLP, disable this option.
7°) The button at the right runs a full probing: TiLP will search for all link cables and all handhelds. This take some time (~20 seconds).
Beware: probing the old non-FLASH handhelds thru SilverLink may not work...
The list at the bottom of the box is used to list probed devices (cables+calcs).
It always list SilverLink cable and USB devices, no more. If you want to get more devices, you have to click the 'Search' button.
Real cables :

| BlackLink or GrayLink | ParallelLink | Silver/Direct Link
| Windows | Linux | Windows | Linux |
port #1 | COM1 | /dev/ttyS0 | LPT1 | /dev/parport0 | Cable #1
port #2 | COM2 | /dev/ttyS1 | LPT2 | /dev/parport1 | Cable #2
port #3 | COM3 | /dev/ttyS2 | LPT3 | /dev/parport2 | Cable #3
port #4 | COM4 | /dev/ttyS3 | N/A | N/A | Cable #4

Note that SilverLink or DirectLink cables are counted in the order they have been plugged.
Imagine you have a Titanium handheld with both SilverLink and DirectLink cables (it's possible !). SilverLink cable will be on port #1 and DirectLink on port #2.
Imagine you have a TI84+/SilverLink and a Titanium/DirectLink, then SilverLink -> port #1 and DirectLink -> port #2.
Note : your handheld with DirectLink must be ON before doing any operation !
Virtual cables :

| VTi | TiEmu
null | automatic | automatic
port #1 | Always VTi | TiLP or TiEmu
port #2 | TiLP or TiEmu | TiLP or TiEmu

With TiLP2, you will always set the port to null. The framework will choose the right port for you.
If you want to use TiLP for exchanging data with an emulator (such as VTi under Windows or TiEmu under Linux/Win32), you will have to select Vti or TiEmu. TiLP must be launched AFTER the emulator.

## 3.2 General Options

This part has been greatly simplified in TiLP2. There are now few options they can be set-up in 2 ways:
- by the Options box,
- by the left/right popup menus.
1°) File displaying: determine whether TiLP will display all files or TI files only.
2°) File/Variables : when this box is checked, TiLP will ask for confirmation for operations such as deleting files, overwriting files, or overwriting calculator variables (a directory listing is performed before sending any variable).
3°) Path : request TiLP to send variables to the current folder (local) or to the original folder (full). This works only with TI9x calculators (89/92/92+/V200).
This option is now disabled for 2 reasons:
- TiLP have no way to know the default folder where variables will be placed,
- TiLP is now able to send variables directly to a given folder.
4°) Receive as : determine the way TiLP will save received variables. In single mode, TiLP saves each variables into its own file. In group mode, TiLP saves the set of variables into a single file (called group).
Note: this option does not apply to TI82/85 yet. Multiple variables are always saved at once (single or group). Use the popup menu to degroup the file if needed.
5°) Backup/Restore with : determines whether TiLP2 will use backup/group files (as TiLP and TI-GRAPH LINK software) or TIGroup files (like Ti-Connect does) for backup and restore operations.
As you will see in the remote popup menu, you can (un)check the Path and the Receive as. Same apply for the local popup menu by the Options sub-menu.

## 3.3 Screenshot Options

This box is accessible only from the Screenshot box (see later) :
Screen Format :
- screen mode : the TI89 calculator has an interesting peculiarity: its screen (LCD) is smaller than one in a TI92(+), but the real screen (in terms of memory) has the same size as a TI92(+). You can see the LCD as a rectangular window. If you select the full button, TiLP will display the whole TI89 screen from the calculator's memory; otherwise, it will only display the portion visible on the actual TI89's screen (LCD).

- gray-scale : the emulate button may be useful for people who want to release screenshots on their websites. When this button is checked, TiLP saves images using emulated grayscales (that is to say, it replaces the black pixels with dark pixels and white pixels with green pixels). In fact, images saved by this feature look just like those gotten from VTi.
File Format : TiLP can capture the calculator's screen and save the image in many different formats : PNG, JPEG, XPM, BMP. PDF & EPS are mostly document formats.
