Recalling Sotred Data from a Diskette or Cassette
''Note:'' The Terminal Emulator II module does not provide a means to retrieve data stored on a diskette or cassette. To do so, you will need an Extended BASIC module (sold separately). The following is an Extended BASIC program which will retrieve data stored on a

''Note:'' When using a cassette, the OPEN in line 120 should have FIXED 80 instead of VARIABLE 80. Also with a cassette, there is no EOF marker on the tape; the program ends with an I/O error when all the data has been read.
 
===File Transfer===
 
The module's file transfer feature enables you to transfer a file from a mass storage device connected to your computer to a mass storage device connected to another computer system, without having to load the file into your computer's memory first. The other system can also transfer files to your computer. This enables you to exchange programs with your friends, as well as send and receive files of information from a data-base service. (Note: Check with the data-base service to find out whether the service makes provisions for transferring files.)
 
To perform a file transfer, the following conditions must be met:
 
:■ The TI Disk Memory System or a compatible cassette recorder must be properly connected to your computer and turned ON. If you're using a cassette recorder, it must be connected to the triple-plug end of the Cassette Interface Cable.
:■ The other system must follow the protocols of the Home Computer. (See "Transmission of Graphics and Sound" for information.)
 
If the file transfer is taking place between two disk systems, you may transfer a program or a data file. If the transfer is taking place between two cassette recorders, you can only transfer a fixed-length data file with records that have a maximum length of 192 bytes. A file stored on cassette ''cannot'' be transferred to a disk system. A diskette-to-cassette transfer can be performed, ''provided'' the diskette file is a fixed-length data file with records having a maximum length of 192 bytes. However, to transfer data from a diskette to a cassette, the fixed length of the data file should be 40 or more. Otherwise, the transfer occurs too slowly, and the sending system may end the transfer before it's complete.
 
====File Transfer to Another System====
 
To transfer a file from your system to the other system, hold down the '''CTRL''' key and press '''4''' (TRANSFER). The module then displays the following:
 
::PLEASE ENTER DEVICE NAME
 
::TO TRANSMIT DATA FROM
 
The device names which you may enter are DSKl, DSK2, and DSK3 (for TI Disk Drives 1, 2, and 3) or CSl (for cassette recorder 1). Type the name of the device from which you are transferring the file and then press '''ENTER'''.
 
The displays that appear next depend on whether you're using a disk
system or a cassette recorder.
File Transfer from Diskette
If you indicate that the transfer will take place from a TI Disk Memory
Drive, the module asks you to enter the name of the file you wish to
transfer to the other system. Make sure that the diskette with the
desired file is inserted into the proper disk drive. Then type the file
name and press ENTER. (Note that you do not need to include the disk
drive number as part of the file name. For example, a file named
TEST80 that's located in Disk Drive One is simply entered as TEST80.)
If the file that you are transferring is a program file, is in internal
format, or has variable-length records, the file transfer starts
automatically. If not, the module 􀁈sks whether the file should be sent as
7-bit data or 8-bit data. If the file only contains data with standard
ASCII upper and lower case letters and punctuation (no control
characters), select option 1 for 7 Bit Data. If the file includes ASCII
control characters, select option 2 for 8 Bit Data. The file transfer
requires less time with the 7-bit option than it does with the 8-bit
option. Once you select the data bits, the file transfer begins. Note: Files
stored on diskette which have variable-length records or an internal
formaJ file are automatically sent as 8-bit data.

Progress."
