Page 4: 1 Introduction
1 introduction the quatech asynchronous serial device driver set for os/2 is a software package which enhances the serial communications capabilities of personal computers using the ibm os/2 operating system, version 2.11 or higher. 1.1 features { support for up to 32 com ports { compatible with all...
Page 5
1.2 supported serial port adapters { all quatech serial adapters { standard (legacy) single serial port hardware such as built-in motherboard ports. { multiport serial adapters from manufacturers other than quatech are not supported. Performance is enhanced by the interrupt status register found on ...
Page 6: 2 Installation
2 installation this device driver set is designed to be a direct replacement for software modules supplied by ibm in the os/2 product. Installation is simple, and changes needed in other portions of a currently working system are minimal. A system backup is suggested before installation. If "serial ...

will other serial ports made by manufacturers other than quatech be used? Quatech's device drivers will operate any serial port that appears to be a standard (legacy) serial port. For these ports, record the port's base address and irq. Quatech's device drivers will not operate third-party multipo...

Port starting port number, 1 or 2 decimal digits the first port on the adapter. The other ports on the adapter follow in contiguous sequence. For example, to install a quatech qs-100 four-port adapter for com9 through com12, use "9" or "09". Io base i/o address, 3 or 4 hex digits the base i/o addres...

2.3.3 quatech intelligent "q-suffix" series products parameter format: (id,mem,port,io,irq) id quatech adapter id "esi" for quatech esi-xxxq intelligent 8-port adapter any other value will cause an installation error. Mem memory window address, five hex digits the hexadecimal base address of the mem...

2.3.4 quatech pcmcia serial port adapters do not place parameters on the qcom.Sys command line for these products. The client device drivers take parameters for pcmcia serial ports. See the client driver documentation for details. 2.3.5 third-party pcmcia cards single-port serial cards and client dr...

2.3.6 all other serial ports (including quatech "ds" two-port adapters) parameter format: (port,io,irq,flags) port port number, 1 or 2 decimal digits the port number. For example, to install a com9, use "9" or "09". Io base i/o address, 3 or 4 hex digits the base i/o address for the serial port. For...

2.4 qvcom.Sys parameters (address/irq masquerading) the qvcom.Sys device driver virtualizes the base address and interrupt level (irq) for serial ports accessed in a dos or windows session. In cases where dos or windows software cannot properly handle the actual hardware settings, the virtual driver...

2.5 optional features the device driver supports some optional features. These features are enabled by adding an option switch to the qcom.Sys command line. The option switch may be placed anywhere on the line outside of parameter groups in parentheses, and it affects all serial ports. Example: devi...

2.5.4 fast rts toggle-on-transmit ("/ft") the /ft option causes the qcom.Sys device driver to aggressively process the rts toggle-on-transmit protocol used in two-wire half-duplex environments. Rts will be deasserted approximately one bit-time following the end of transmitted data. Without this opti...
Page 16: 3 Using The Driver
3 using the driver the drivers can service up to 32 serial ports. The names of these ports range from "com1" to "com32". 3.1 os/2 application software an os/2 application can access any installed serial port from com1 through com32 by specifying the "comxx" name. 3.2 win-os/2 application software th...

Qvcom.Sys provides most of the same dos settings as ibm's vcom.Sys. For full details on these settings, consult the os/2 documentation or online help. Differences between the quatech and ibm drivers are discussed here. It is suggested that these dos settings be left at their default values unless ne...

3.4.2 pcmcia bus quatech multiport pcmcia serial port cards will share a single interrupt between all ports on the card. Interrupt sharing between multiple pcmcia cards is governed by the pcmcia subsystem, and is not supported by this device driver. 3.4.3 isa bus isa (at) bus computers do not suppor...

16550 uarts or 921,600 bps for 16750 uarts. Software may set these baud rates directly by using the appropriate os/2 function calls (ioctl functions 0x43 and 0x63 for baud rates higher than 57,600). If a rate selector jumper is applied, the device driver will accept only baud rates up to 115,200 bps...

Block mode addressing must be used in order to specify an "id" parameter in the qcom.Sys configuration line. 3.8.2 discrete addressing in this mode, each serial port on the adapter is addressed discretely from the other ports. The interrupt status register is not used. Each port is installed as a se...

3.9 limitations 1. Performance is dependent on the computer system in which the software is used. In general, more powerful systems and systems with lighter process loads can accommodate the highest cumulative data throughput. 2. Dma serial ports are used only as standard interrupt-driven ports. 3. ...
