Page 2: 1 General Information
1 general information the quatech, inc. Qsclp-100 provides four rs-232 asynchronous serial communication interfaces for low profile ibm-compatible personal computer systems using the pci expansion bus. The qsclp-100 uses quatech's new enhanced serial adapter design. Legacy serial port data rates are...
Page 3: 2 Hardware Configuration
2 hardware configuration the qsclp-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. Jumpers j2-j5...
Page 4
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 thr...
Page 5: 3 Hardware Installation
3 hardware installation 1. Turn off the power of the computer system in which the qsclp-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. Install the qsclp-100 in any empty p...

4 address map and special registers this chapter explains how the four uarts and special registers are addressed, as well as the layout of those registers. This material will be of interest to programmers writing driver software for the qsclp-100. 4.1 base address and interrupt level (irq) the base ...

4.2 enabling the special registers the qsclp-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 i...
Page 9: 4.4 Options Register
4.4 options register the options register allows software to identify the qsclp-100 as a quatech enhanced serial adapter. It also allows software to set the uart clock rate multiplier. Figure 8 shows the structure of the options register. The powerup default of the options register is all bits zero....
Page 10: 4.4.2 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. This is controlled by the clock rate multipli...
