If you have Microsoft Windows 3.0 or 3.1 ---------------------------------------- Use Microsoft Windows to run the SETUP.EXE program as documented in your Users Guide. The SETUP.EXE Windows program will properly install and configure your ESP card. Uninstall Feature ----------------- A last minute feature added to the SETUP.EXE program is an option to Uninstall your ESP card. This allows a user to remove the ESP's COM port from the system map and clean up any changes made to the SYSTEM.INI and WIN.INI files. How to Uninstall ---------------- If you wish to Uninstall a card, or a particular port, use Microsoft Windows to run the SETUP.EXE program. The first window you see is the 'Card Configuration' window. To uninstall, select the address of the card and press the 'Configure' push button. This will pop up the 'Modify Card Configuration' dialog box. Go to the right hand corner of the dialog box and press the 'Uninstall' radio button. After pressing the 'Uninstall' button, go down to the 'Ok' push button to save the new configuration. This brings you back to the 'Card Configuration' window, at this point you can push the 'Exit and Save' to uninstall the card. If you do not have Microsoft Windows 3.0 or 3.1, but you do have DOS you can use DOSSETUP.EXE or ESPCA.EXE. ESPCA.EXE is a command line oriented configuration program. If you need assistance in configuring the ESP adapter use DOSSETUP.EXE, which provides help screens on each configuration option. -------------------------------------------------------------------- DOSSETUP.EXE ------------ A DOS setup program, DOSSETUP.EXE, has been included that allows you to configure the ESP Communications Accelerators for your system. Run the program from the DOS prompt and select an ESP card to configure. The Address, Port, and IRQ information for the selected card will then be displayed. Use the arrow keys to select the parameter you wish to change. (Note: For new installations and for cards which have been uninstalled, the information displayed represents suggested values and not the information on the card). DOSSETUP.EXE also allows you to select one-time settings (set for the current session of DOS only). These are: 1) FIFO Enabling for all ESP2 cards in your system. 2) Automatic RTS/CTS Flow Control for the currently selected card. 3) UART Baud Rate Multiplier Prescale Value for the selected card. To access these options, select 'Other Settings...' from the Address/ Port/IRQ configuration screen. For every option in DOSSETUP, help text is displayed at the bottom of the screen to assist you in configuring your ESP2 card. DOSSETUP will also detect other serial cards and their IRQs to inform you of possible conflicts. ESPCA.EXE --------- The ESPCA.EXE program runs under DOS, and can configure your ESP Communications Accelerator card. Type ESPCA ? at the DOS prompt to receive help on how to use ESPCA.EXE. The ESPCA program will display: Usage: ESPCA F Axxx:yyy Cxxx:y Ixxx:y Rxxx:y Pxxx:y S Q ? - display this usage information F - initialize all ports to FIFO enabled Axxx:yyy - change I/O address xxx to yyy Cxxx:y - change COM designation for port at I/O address xxx to y Ixxx:y - change IRQ for port at I/O address xxx to y Rxxx:y - enable (y='+') or disable (y='-') RTS/CTS flow control Pxxx:y - set UART baud rate multiplier prescale value (y=0-3) Uxxx - uninstall I/O address (all ports on board) S - skip read configuration step if possible Q - quiet (no screen output) I/O Addresses Each ESP card must have its own I/O Address, and is referred to by that address (the xxx values above). The ESP card is factory-configured to use I/O Address 300 (hex) when the hardware jumper is in the S/W position. You may change the I/O address by moving the hardware jumper from its factory position S/W to the 140, 180, or 280 positions. If a different I/O address is desired, use the A command to store a new S/W address in the ESP card's permanent (nonvolatile) memory. I/O Addresses 100, 140, 180, 200, 240, 280, 300, and 380 are available. For example, to change the ESP card from its factory I/O address of 300 to I/O address 100, type ESPCA A300:100. Each port on an ESP card has a unique I/O address. The I/O addresses for for subsequent ports on a card are multiples of eight. For example, on a two-port ESP card, the first port is referred to by I/O address 300, and the second port is referred to by I/O address 308. Note that these I/O addresses are different than UART I/O addresses (which are associated with COM ports, and have values like 2F8 and 3F8). COM and IRQ Designations You will want to choose a COM designation which does not conflict with an existing port. For example, if your PC has a built-in COM1 serial port, you should designate the ESP port as COM2. COM ports require IRQ assignments. There are de facto standard IRQ assignments based on COM port choice. These are: COM1 IRQ4 COM2 IRQ3 COM3 IRQ4 COM4 IRQ3 To assign COM3 and IRQ4 to the ESP card, type ESPCA C300:3 I300:4 (assuming your ESP card is at the factory I/O address of 300). Note: IRQ conflicts can occur if more than one card attempts to use a given IRQ number at the same time. FIFO Enable Use the F switch to enable extended 1024-byte FIFOs on the ESP card when used in UART mode (1024-byte FIFOs are always used in Enhanced Mode). This often results in increased performance and reliability compared to standard 16-byte 16550A FIFOs. You may wish to include the line: ESPCA F S in your AUTOEXEC.BAT file to enable the larger FIFOs automatically at boot time (the S switch skips the sometimes lengthy "read configuration" step). RTS/CTS Automatic Flow Control The ESP Communications Accelerator can perform automatic RTS/CTS flow control at the hardware level. You may wish to configure software for "no flow control" if you plan to let the ESP card perform automatic flow control. To enable RTS/CTS automatic flow control, type ESPCA R300:+ (assuming your ESP card is at the factory I/O address of 300). Baud Rate Prescaler Your ESP Communications Accelerator can communicate at speeds higher than 115200 bps using the P command, which multiplies baud rates. Baud rates can be doubled, quadrupled, or octupled. The maximum data rate is 8 times 115200, which is 921600 bps. Prescale values range from 0 to 3 as follows: 0 - 1x baud rates (normal baud rates) 1 - 2x baud rates 2 - 4x baud rates 3 - 8x baud rates To set an ESP port for maximum speed, type ESPCA P300:3 (assuming your ESP card is at the factory I/O address of 300). Uninstall Port If you wish to disable all ports on a card, or a particular port, use the U command to set the COM designation to COM0 (disabled). Specifying the lowest I/O port address for a multiport card disables all ports for that card, for example: ESPCA U:140 (disables all ports on card with I/O Address 140) Skip Read Configuration The ESPCA.EXE program reads the configuration information from the ESP card's nonvolatile memory each time it runs in order to display the information. This step takes several seconds to complete. If you do not want to take the time unless necessary, specify the S switch. Quiet Mode Specifying the Q switch results in Quiet Mode, under which the ESPCA.EXE program will produce no standard output. Fixes/Enhancements to Hayes ESP Communications Accelerator Setup Diskette 2.0E SETUP.EXE v1.03 - Fixed an invalid message about the SW jumper position, that indicated the jumper was not in the SW jumper position when it was. This message only appeared when changing the IO address. DOSSETUP.EXE v1.0 - Added DOSSETUP.EXE program to aid in configuring the ESP2 adapter in the DOS environment.
