    QSP200CL.SYS, and a card Enabler, QSP200EN.EXE. Both of these programs are executed from DOS (before entering Windows) and allow operation of the QSP-200/300 in both the DOS and Windows 3.x environments. For optimal operation, however, the Client Driver is the preferred method of installation and configuration.

  • Page 22: Qsp-200/300 Client Driver For Dos

    4.1 QSP-200/300 Client Driver for DOS In order to use the QSP-200/300 Client Driver, the system must be configured with Card and Socket Services software. Card and Socket Services software is not provided with the QSP-200/300. IMPORTANT: Some versions of Card and Socket Services dated before 1993 do not support general purpose I/O cards.

  • Page 23: Command Line Options

    4.1.2 Command Line Options The QSP-200/300 Client Driver accepts up to eight command line arguments from the user to determine the configuration of the QSP-200/300. If any arguments are provided, the Client Driver will attempt to configure any QSP-200/300s with the options specified in the order they are entered on the command line.
  • Page 24 If this option is omitted, the default setting is RTS-CTS modem control handshake disabled. See the Hardware Information section for more information. instructs the Client Driver to disable the QSP-200/300's interrupt status register and enable the Scratchpad registers of the individual UARTs. This option is only required in very rare cases where an application program requires access to the UART's Scratchpad register.

  • Page 25: Qsp-200/300 Client Driver Examples

    In example 3, a single command line argument is provided. The Client Driver will attempt to configure a QSP-200/300 inserted into socket 0 with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the card will not be configured. In addition, if a QSP-200/300 is inserted into any other socket, it will not be configured.
  • Page 26 In example 5, three command line arguments are provided. The Client Driver will first attempt to configure a QSP-200/300 inserted into any socket with a base address of 300H and IRQ 5. If address 300H or IRQ 5 is unavailable, the Client Driver will proceed to the second command line argument and attempt to configure the card with a base address assigned by Card and Socket Services and IRQ 10.
  • Page 27 QSP-200/300 is to be installed. In this example, the Client Driver will attempt to configure a QSP-200/300 inserted into socket 0 with a base address of 300H and IRQ 5. If the card is inserted into socket 1, the Client Driver will attempt to configure it with base address 340H and IRQ 10.

  • Page 28: Common Problems

    Some versions of Card and Socket Services dated before 1993 do not support general purpose I/O cards. If after careful installation of the Client Driver the QSP-200/300 does not configure or operate properly, an updated version of Card and Socket Services may be required. Card and Socket Services software is available from Quatech Inc.
  • Page 29 QSP-200/300 Enabler may interfere with its operation and with the device(s) it controls. The QSP-200/300 Enabler does not support automatic configuration of adapters upon insertion, more commonly referred to as "Hot Swapping". This means the adapter must be installed in one of the system's PCMCIA sockets before executing QSP200EN.EXE.

  • Page 30: Command Line Options

    4.2.1 Command Line Options To configure a QSP-200/300 in the system, the Enabler requires one command line argument from the user to determine the configuration of the card. This argument must be enclosed in parenthesis and within the argument, any or all of the following parameters may be specified...
  • Page 31 Enabler to release the resources previously allocated to the QSP-200/300. When the 'R' option is used, any settings specified by the 'B', 'I', 'U', and 'E' options are ignored. This option must be omitted when installing a QSP-200/300 into the system.

  • Page 32: Qsp-200/300 Enabler Examples

    Example 2 QSP200EN.EXE (s0,b300,i5) In example 2, the Enabler will configure the QSP-200/300 in socket 0 with a base address of 300H and IRQ 5 using a configuration memory window at segment D000. The output drivers will be configured for full duplex operation (always enabled), the RTS-CTS handshaking will be disabled (loopback mode), and the interrupt status register will be enabled.
  • Page 33 Example 5 QSP200EN.EXE (s0,b300,i5,r) In example 5, the Enabler will release the configuration used by the QSP-200/300 in socket 0 using a configuration memory window at segment D000. The base address and IRQ parameters are ignored and may be omitted.

    QSP-200/300 Enabler, the lowest socket number in the system is designated socket 0. Card and Socket Services Software: In order to use the QSP-200/300 Enabler for DOS, the system MUST NOT be configured with Card and Socket Services software. If a Card and Socket Services software is installed, the QSP-200/300 Enabler may interfere with its operation and with the device(s) it controls.

  • Page 35: Os/2 Installation

    5 OS/2 Installation In order to use the QSP-200/300 Client Driver for OS/2, the system must be configured as follows: 1. The system must be running OS/2 2.1 or later. 2. OS/2 PCMCIA Card and Socket Services support must be installed. If PCMCIA support was not selected when OS/2 was installed, it can be added using the Selective Install facility in the System Setup folder.

  • Page 36: Command Line Options

    In example 1, the Client Driver will attempt to configure the QSP-200/300 as COM3 through COM6. If COM3, 4, 5, or 6 already exists in the system, the QSP-200/300 will not be configured. Furthermore, only one QSP-200/300 can be installed in this system.

  • Page 37: Configuring With "User Assigned" Resources

    As mentioned in the previous section, allowing the OS/2 Plug-and-Play system to assign the hardware resources to the QSP-200/300 is ideal for OS/2 programs but can be a problem if DOS and/or Windows applications will be accessing the serial ports. This is because most DOS applications write directly to the communications hardware and the Windows' Control Panel also wants to know the hardware configuration of the serial ports.

    "system assigned" resources. Use the "Configuration Manager" program to examine the I/O address range assigned to the QSP-200/300. If this range does not begin on an even 32 byte (20H) boundary, the QSP-200/300 will have to be installed using "user assigned" resources to force a valid configuration.

  • Page 41: Hardware Information

    The QSP-200/300's four asynchronous serial ports are implemented using 4 standard 16C550 UARTs. Each of these UARTs requires 8 bytes of I/O space and when enabled which requires the QSP-200/300 to be located on an even 32-byte (20H) boundary (e.g. 300H, 320H, 340H, etc.).

  • Page 42: Auxiliary Channel Configuration

    6.3 Auxiliary Channel Configuration An auxiliary channel is provided which allows for handshaking between a QSP-200/300 RS-422/485 port and a peripheral device. This auxiliary channel may be configured in one of two ways: Ÿ RTS-CTS handshake enabled. Ÿ handshaking is disabled.

  • Page 43: Auxiliary Channel: Handshaking Disabled

    6.3.2 Auxiliary Channel: Handshaking Disabled The QSP-200/300 ports may be configured so that the RTS-CTS handshake is disabled. This is the default configuration. In this configuration, RTS and CTS from the 16C550 UART will be looped back to each other. In addition, the auxiliary output and input signals will be looped back to each other.

  • Page 44: Termination Resistors

    RS-422 100 ohm 1/2W resistor 6.5 2-Wire Operation The QSP-200/300’s ports may be configured for either full duplex or half duplex operation. By default, the RS-422/485 ports are configured for full duplex operation with the RS-422/485 output drivers always enabled.
  • Page 45 Selection of half duplex mode operation is dependent upon the configuration software and/or the operating system used. Each of these, however, ultimately control the half duplex mode by accessing the PCMCIA Configuration Register on the QSP-200/300. CAUTION: When operating in half duplex mode, the transmitter output drivers must be disabled before receiving and information.
