1. Each 16C550 UART contains 8 I O registers The last of these registers located at Base address 7 is referred to as the Scratchpad Register and provides no functionality to the UART In place of this Scratchpad Register the QSP 100 implements an interrupt status register which can be accessed at Base address 7 of any UART The purpose of the interrupt status register is to give the software programmer an easy way to inspect the interrupt state of the entire QSP 100 with a single input operation The format of the interrupt status register is shown below D7 D6 D5 D4 D3 D2 D1 DO 0 0 0 0 Intr D Intr C Intr B Intr A When one or more UARTs have interrupts pending the associated bit s in the interrupt status register are set to logic 1 When all the pending interrupts have been serviced for a specific UART its interrupt status bit will be cleared to logic 0 automatically When all the pending interrupts from all UARTs have been serviced the entire interrupt status register will return logic 0 The application program should not exit its interrupt service routine until all pending interrupts from all channels have been serviced interrupt status register 0 or no additional interrupts will be received If an application requires the UARTs Scratchpad Registers the interrupt status register can be disabled using the p option on the QSP 100 Client Driver for DOS or the DOS Enabler command li2.

6. 1 Introduction The QSP 100 provides four independent RS 232 asynchronous serial communications interfaces for systems equipped with PCMCIA Type II and or Type II expansion sockets The QSP 100 is a PCMCIA Type II 5 mm card and is PCMCIA PC Card Standard Specification 2 1 compliant The QSP 100 s serial ports are implemented using 16C550 Universal Asynchronous Receiver Transmitters UARTs which are the recommended communications interface for multitasking environments and with applications involving high data transfer rates The QSP 100 s four serial ports are addressed in a single 32 byte I O block for simplified programming and all four channels share a common interrupt IRQ A special interrupt status register is also available to simplify the software required to service multiple serial ports in an interrupt driven environments QSP 100 User s Manual 1 2 DOS Windows 3 x Installation Two configuration software programs are provided with the QSP 100 a Client Driver QSP100CL SYS and a card Enabler QSP100EN EXE Both of these programs are executed from DOS before entering Windows and allow operation of the QSP 100 in both the DOS and Windows 3 x environments For optimal operation however the Client Driver is the preferred method of installation and configuration The table below highlights the differences between these programs Client Driver recommended Enabler not recommended File name QS

IRQ resources are available For OS 2 Warp users the RMVIEW utility may be useful in finding resource conflicts Type rmview at an OS 2 command prompt for details When using system assigned resources if the user knows the port number is available then the system may not have sufficient resources available to configure the QSP 100 Again the RMVIEW utility provided with OS 2 Warp may be useful in determining the problem Regardless of the configuration method each command line argument specifies the first of four COM ports for the QSP 100 If any of these COM ports are already installed the Client Driver will not load Parameter Overlapping When installing the QSP 100 each command line argument specifies the first of four COM ports If these arguments overlap the Client Driver will not load For example it is illegal to specify QSP100 SYS COM3 COM4 because the first argument requests COM3 COM6 and the second argument specifies COM4 COM7 Insufficient Number Of Command Line Arguments The QSP 100 command line must contain at least one command line argument for each QSP 100 to be installed QSP 100 User s Manual 19 4 Windows 95 Installation Windows 95 maintains a registry of all known hardware installed within the computer Inside this hardware registry Windows 95 keeps track of all the computer s resources such as base I O addresses IRQ levels and DMA channels In the case of aPC Card PCMCIA type board Wind
