    The QSC(LP)-100 is supported under several popular operating systems and environments. Contact the sales department for details on current software offerings. Most device drivers are available for download from the Quatech world wide web site at http://www.quatech.com. QSC(LP)-100 User's Manual...
  • Page 7: Hardware Configuration

    2 Hardware Configuration The QSC(LP)-100 is automatically configured at boot time by the computer's BIOS or operating system. There are no required switches or jumpers to set for installation. This chapter lists a number of optional jumper settings that control various hardware features.
  • Page 8: Force High-Speed Uart Clock (X2, X4, Or X8, J3-J5)

    2.3 Force High-Speed UART Clock (X2, X4, or X8, J3-J5) These jumpers force an increase of the UART input clock frequency by a factor of two, four, or eight. This feature can allow legacy software to use baud rates above 115,200 bits per second. It is also useful if the serial port device driver does not directly support setting the higher baud rates through the Options Register (see section 4.4).
  • Page 9: Hardware Installation

    3 Hardware Installation 1. Turn off the power of the computer system in which the QSC(LP)-100 is to be installed. 2. Remove the system cover according to the instructions provided by the computer manufacturer. 3. Make any desired optional jumper setting changes. 4.
  • Page 10: Address Map And Special Registers

    The base address and IRQ are automatically detected by the device drivers Quatech supplies for various operating systems. For cases where no device driver is available, such as for operation under DOS, Quatech supplies the "QTPCI" DOS software utility for manually determining the resources used. See section 6.3.1 for details.
  • Page 11: Enabling The Special Registers

    4.2 Enabling the Special Registers The QSC(LP)-100 contains two unique registers, an Interrupt Status Register and an Options Register. These registers are enabled when the SPAD jumper (J6) is removed (factory default). They replace the UART Scratchpad Register on accesses to register address 7. The Interrupt Status Register and Options Register are accessed through the scratchpad location of any UART.
  • Page 12: Options Register

    4.4 Options Register The Options Register allows software to identify the QSC(LP)-100 as a Quatech Enhanced Serial Adapter. It also allows software to set the UART clock rate multiplier. Figure 9 shows the structure of the Options Register. The powerup default of the Options Register is all bits zero.
  • Page 13: Clock Rate Multiplier

    4.4.2 Clock Rate Multiplier A standard RS-232 serial port operates at a clock speed of 1.8432 MHz. In order to achieve higher data rates, Quatech Enhanced Serial Adapters can operate at two times, four times or even eight times this standard clock speed.
