FOR IMMEDIATE RELEASE CONTACT: Stan Hayes, 404/325-0722 MCI MAIL: SHAYES 263-5738 COMPUSERVE: 76576,1524 CROSSTALK FOR WINDOWS -- Program Features Overview Terminal Emulation -- With accurate emulations of DEC VT102, IBM 3101, and ANSI terminals, you'll be able to access other PCs, minicomputers, mainframes, and information services (such as CompuServe and Dow Jones News/Retrieval Service). File Transfer -- Full-featured file transfer support allows data exchange with other hosts. In addition to our proprietary Crosstalk and DART protocols, we support XMODEM, YMODEM, ZMODEM, Kermit, CompuServe B, and ASCII upload and capture. With DART, more efficient file transfers are possible. DART has options for transferring only files that are new or have changed. DART also can pick up where it left off if a file transfer is interrupted. These automatic features are extremely useful for any level of file transfer activity. Programming Language -- A powerful programming language lets you automate communications in the Windows environment. The easy- to-understand language allows you to write "scripts" to perform repetitive tasks. Example scripts are provided for MCI Mail, CompuServe, Dow Jones News/Retrieval Service, and many other on-line services. A special "Learn" script is included to write other log-on scripts for you. Dynamic Data Exchange (DDE) -- Support of the Microsoft DDE protocol allows Crosstalk to directly interact with other Windows applications like Excel. An example is included which calls CompuServe, picks up stock quotes, and feeds them directly into an Excel spreadsheet. Mouse Support -- Like all Windows applications, Crosstalk may be operated from the keyboard or a mouse, and has standard pull- down menus. This makes dealing with a menu-driven host even simpler. Just double-click on the menu item you want, and let Crosstalk transmit the choice for you. It will even press the "Enter" key after sending your choice. When emulating a DEC or IBM 3101 terminal, you can move the host cursor by pointing to where you want it, and clicking the mouse's right button. Programmable Keys -- You can use the 48 programmable function keys for single keystroke operation of host responses or scripts. In addition, the function keys can be "pressed" by clicking on-screen icons with the mouse or by a customized pull-down menu selection. Connections Supported -- Crosstalk for Windows supports direct "hard-wired" host connections and all popular modems, including high-speed, error-correcting modems. Settings for over 30 modems are included. Individual modem options may be customized according to user preference. Background Operation -- You get true "background" operation for transferring files or performing any Crosstalk function while you use other Windows applications. Cut and Paste -- You can access Notepad from within Crosstalk to easily edit text, like a mail message, and paste it to the host. Phone Book -- Crosstalk has an integrated phone book for storing the numbers of your host computers. The phone book allows you to easily save and recall all settings for any host computer. Review Buffer -- With the adjustable scroll buffer of up to 64K, you can review information that has scrolled off the screen. You can select information in the buffer and copy it to the clipboard, a file, the printer, or a notes area. Capture Options -- While you're online, you can capture data directly to a file and/or the printer. It's great for recording host sessions for later playback, cutting and pasting, or an audit trail. Printer Control -- Crosstalk's menus also include choices for entering headers and footers for your printing. You can also change your printer and its settings, just like you can from the Windows Control Panel. Help System -- The on-line help system has an index of over 60 help screens, giving you easy access to more detailed information when you need it. CROSSTALK FOR WINDOWS - Specifications and Operating Technical Features Program Specifications: Terminal Emulations Supported: DEC VT102 and VT52 (including "double size" characters), IBM 3101 (character mode), BBS- style ANSI color terminal, and CompuServe VIDTEX graphics terminal (medium and high resolution modes). File Transfers Supported: Crosstalk, DART (our proprietary transfer protocol which supports redundant file skipping and partial file recovery), XMODEM, YMODEM, ZMODEM, Kermit, CompuServe B, and ASCII upload and capture. Connections Supported: In addition to direct "hard-wired" host connections, Crosstalk supports most popular asynchronous auto-dial modems, including high-speed, error-correcting modems. Speeds of 300 to 19,200 bps are supported. Parity settings include None, Odd, Even, Mark, and Space. Answer Mode: Unattended answer mode includes password protection and directory restriction options. Script Language: Based on Crosstalk Mk.4's powerful CASL language, it adds extensions for the Windows environment such as the ability to create custom dialog boxes and execute DDE commands. The language includes over 250 commands, functions, and statements. Requirements: Requires Version 2.1 or later of Microsoft Windows/286 or Windows/386 for operation. Crosstalk for Windows needs approximately 500K of disk space and 150K of RAM. Documentation: User's Guide-156 pages, includes listing of error messages, glossary, and index. Programmer's Reference-334 pages with index. Operating Technical Features: Mouse Operation: Double clicking the left button in the terminal screen area causes the string pointed to by the mouse to be sent to the host. Optionally, only a single character will be sent. With DEC amd IBM 3101 terminal emulation, double clicking the right button causes cursor movement keys to be generated, moving the host cursor from its current position to the position pointed to by the mouse. Double clicking the displayed communications settings (e.g. terminal type) will cause them to cycle through the available options. Double clicking on "Capture" and "Printer" indicators turns capture and printer on and off. Double clicking the on-line timer, will toggle scroll mode for reviewing text. In scroll mode, the mouse is used to select text for copying. On-screen function key labels may be clicked on to simplify routine operations. Notes Area: Each phone book entry has its own message area that can contain up to 255 characters. If desired, this note may be displayed each time the host is called. Function Keys: The 48 user-defined function keys can send host responses, and execute Crosstalk commands or scripts. The function keys optionally appear in banks of twelve at the bottom of the screen. (If only the first twelve keys are defined, only one row of twelve keys will appear at the bottom of the screen.) The user may label each function key for additional ease of use. The size of the function key label displayed is automatically adjusted according to the text for the label and the number of active keys. The user may choose to have some or all function keys available through a pull-down menu. The user also may assign the keyboard accelerator of these menu items. Display: One of four terminal screen fonts may be selected with sizes ranging from 7x7 to 20x12. The colors of the terminal screen background, normal text, bold text, etc. are user-selectable. Script Programming Language Highlights: The programming language is a high-level language with a wide range of statements, functions, variable assignments, system and session variables, mathematical, logical, and string operators. Scripts may be stored in full-text and/or compiled forms. All system variables are accessible via DDE. Here are a few samples of the commands for various programming needs: Flow Control: WHILE...WEND, GOTO, GOSUB, CHAIN, JUMP, LABEL, RETURN, IF... THEN...ELSE, REPEAT...UNTIL. File I/O: EOF, EOL, EXISTS, GET, LOC, SEEK, WRITE, WRITE LINE, OPEN, PUT, READ, READ LINE, DEFINPUT, DEFOUTPUT.
