TERM.EXE - TERMINAL EMULATION PROGRAM FOR SERIAL PORTS IMPORTANT NOTE: The TERM program is supplied only as an aid for the initial setup of your BayTech unit and is not used in operations. This short program simply allows your PC to emulate a dumb terminal (in the event that you do not have your own terminal emulation software), thus allowing you to communicate more easily with the configuration mode of the BayTech unit. Once setup has been completed, this program is no longer used or needed unless further configuration changes of the unit are required at a later date. TERMINAL EMULATION INSTRUCTIONS Connect a cable between the COMX port of the PC (X = 1 or 2) and the configuration port of the BayTech unit. For configuration port, pinout and recommended cabling, see your Owner's Manual. Load DOS into system. Place BayTech software diskette into disk drive. There are three possible ways to load TERM from your system prompt: 1. Type TERM from your system prompt 2. Type TERM 1 from your system prompt 3. Type TERM 2 from your system prompt TERM defaults to COM1 at the parameters you have COM1 set up for in DOS when you type TERM from your system prompt. You may change the default settings for TERM by typing TERM 1 for COM1 or TERM 2 for COM2. Default parameters for COM1 and COM2 are dictated by your PC's initial setup. The program will respond with an identification block and then a configuration menu for the PC COM port. You are now in the dumb terminal mode. NOTE: Your BayTech unit powers-up from the factory at 9600 baud rate, 8 word size, 1 stop bit and no parity, with XON/XOFF disabled. If the PC COM port does not match this configuration, you may reconfigure the COM port by entering Alt-C and following the menu to set the port to match the baud rates, word size, stop bits, parity and handshaking of the BayTech unit. COM1 or COM2 may be selected. If no COM2 card is installed, the terminal emulation program will prevent you from selecting COM2. Once configuration of the PC COM port is complete, depress the Enter key, and you will return to the dumb terminal mode. If you entered TERM by typing TERM 1 from your system prompt, any changes made to COM1 will be retained when you enter TERM by typing TERM or TERM 1 from your system prompt. If you made any changes to COM2 when entering TERM by typing TERM 2 from your system prompt, these changes will be retained when you re-enter TERM by typing TERM 2 from your system prompt. Interface lines - RTS, CTS, DSR, DTR - between the PC and Your BayTech unit should be high. (Refer to upper right hand corner of the CRT for interface line status. These indicate the hardware handshaking line conditions as seen by the PC.) If these signals are not high at this point, check the cable. The DCD line is not looked at by the terminal emulation program. You are now in a dumb terminal or terminal emulation mode with full duplex communication. Any characters you type from the keyboard will be transmitted out of the PC COM port to the BayTech unit but will not appear on the CRT screen. Any characters received by the PC COM port from the BayTech unit will be displayed on the CRT screen. You may now reconfigure the BayTech unit from the keyboard of the PC. This is accomplished by sending Control-T followed by CAPITAL C (except Stat Mux). For the Stat Mux send Control-T only. The Control-T and capital C will not appear on the CRT screen, the BayTech unit will respond with a configuration menu. NOTE: Depressing the F1 key automatically sends this two- character sequence to the BayTech unit. The F1 key does not apply to Stat Mux and if the H Series control character has been changed. If no menus appear, this indicates that an incorrect character sequence has been received. If this occurs, resend Control-T and capital C manually or depress F1 key. You should also verify that your cables and configurations are correct. Continue following the menus. If you have any questions about this procedure, refer to the configuration section of the owner's manual. SMODE.EXE You may configure your PC com port to communicate at serial speeds up to 115.2K bits per second by using the SMODE.EXE program. SMODE is very similar to the MODE command in DOS. You should copy SMODE.EXE to your PC's root directory and then add - 2 - the SMODE command to your AUTOEXEC.BAT file. See your DOS manual for instructions on editing your AUTOEXEC.BAT file. The SMODE command has a maximum of 5 parameters: com port, baud rate, parity, word size, and stop bits. You may review various examples by typing SMODE from your system prompt. Valid com ports are COM1 through COM4. Valid baud rates are 50, 75, 110, 135, 150, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200 bits per second. Valid parity is N for None, M for Mark, S for Space, E for even, and O for odd. Valid word sizes are 5, 6, 7, or 8 bits. Valid stop bits are 1 or 2 bits. REMCONFG.COD This file contains a 2 byte control code (94H 2CH) that allows the user, when the file is sent to the COMPOSITE port via modem/communication software, to access the remote configuration/diagnostics mode of the Stat Mux unit. - 3 -
