Holding down the '''CTRL''' key and pressing 1 instructs the Home Computer to speak all the text displayed on the screen. Pressing '''CTRL 1''' (SPEAK) has no effect unless the TI Solid State Speech<sup>TM</sup> Synthesizer is properly attached to your Home Computer. For information on accessing text-to-speech in a TI BASIC program, see Appendix C. ''Note:'' You cannot use '''CTRL 1''' when you are in the graphics mode.
=====Control 2 (OUTPUT)=====
Holding down the '''CTRL''' key and pressing '''2''' (OUTPUT) allows you to transmit a page of currently displayed data to a printer or a mass storage medium, such as a cassette tape or diskette. Once you press '''CTRL 2''' (OUTPUT), the module asks you to enter the device name. The module accepts any of the following device names, provided the device is properly connected to the computer and turned ON.
When the computer finishes writing a page, the previously displayed data reappears. To output additional data, press '''CTRL 2''' (OUTPUT) again. The program then asks if you wish to OUTPUT TO PREVIOUS DEVICE and offers you the choice of pressing '''1''' for "yes" or '''2''' for "no." To save additional data, enter '''1'''. (''Note:'' If you are saving data on a disk system, the file is closed when you press '''2''' for "no." Once the file is closed, you cannot add additional information to it.)
=====Control 3 (CANCEL)=====
Pressing '''CTRL 3''' (CANCEL) cancels the following functions while they are in progress: the automatic log-on sequence, file transfer, and output to a mass storage device.
=====Control 4 (TRANSFER)=====
Holding down the '''CTRL''' key and pressing '''4''' (TRANSFER) enables you to transfer a file of information from your cassette or diskette to the other system. See the "File Transfer" section for full information.
=====Control 5 (WRAP)=====
'''CTRL 5''' (WRAP) controls the status of the wrap-around feature. The module begins with WRAP automatically ON. With the wrap-around feature on, the module breaks lines at blank spaces whenever possible and continues long lines of text on the next line instead of extending the text beyond the right screen boundary. When you press '''CTRL 5''' (WRAP), the WRAP feature changes to OFF. With the wrap-around feature off, the text is displayed just as it is transmitted by the other system and may extend beyond the right screen boundary. To turn WRAP back on again, press '''CTRL 5''' once more.
If the WRAP is off and you are receiving data, the module displays the first portion of each incoming line of information. (The number of characters that are displayed depends on the column width you selected on the COMMUNICATION SETUP display.) The final position in the line shows the rest of the transmitted line one character at a time. To view the data which extends beyond the screen boundaries, use the arrow keys as explained in the section, "Reviewing Data with the Arrow Keys." Since many systems pause after sending 24 lines of data, you might wish to review the data at the end of each page.
=====Control 6 (CASE)=====
'''CTRL 6''' (CASE} controls the case of the characters to be sent to the remote system. Unless you change the case setting, the module sends upper case letters. To change to lower case, hold down the '''CTRL''' key and press '''6'''. To send upper case again, hold down the '''CTRL''' key and press '''6''' again. Note: The remote computer controls the case of the characters you receive.
=====Control 7 (PAGE)=====
This feature allows you to scroll the text on your display up or down 24 lines at a time, or left or right one page at a time, as determined by the column width you selected. For details, see the section "Reviewing Data with the Arrow Keys."
=====Control 0 (EXIT)=====
Pressing '''CTRL 0''' (EXIT} returns the computer to the master title screen, ending a session with the module. The EXIT sequence closes all open files, protecting any data stored on your disk system. All data not saved on a mass storage device is lost. Note that the EXIT key sequence does not "sign off' with the other system. For information on signing off, refer to "Ending Data Exchange."
'''IMPORTANT:''' Pressing '''QUIT''' also returns the computer to the master title screen, but it does not close all open files. If you exit the module by any means other than '''CTRL 0''', such as pressing '''QUIT''' or turning the computer console off, the data you have saved on diskette may be lost.
=====Function V (DELETE)=====
Pressing '''FCTN V''' (DELETE} transmits a DELETE control character (ASCII 127) to the other system. This is useful if you make a typing error while transmitting a code or other information to the other system. If the other system accepts the signal, it deletes either the most recent character you sent or the most recent line of text you sent. (To find out which is deleted, consult the other system's instruction manual.)
=====Control . (ESCAPE)=====
Pressing '''CTRL.''' (ESCAPE} sends an escape (ESC) signal to the other system. Since the results of pressing ESCAPE are not always the same. check the other computer system's owner's manual for the meaning of this function.
