Quatech OS/2 Serial Port Device Drivers ("QCOM")
Release 3.23
27 November 2001
The printed documentation is now available only in the form of an
Adobe Acrobat (PDF) file. It contains no known errors. If you do
not have a copy of the free Adobe Acrobat reader, please obtain one from
Adobe Systems at http://www.adobe.com.
The Quatech driver set is a drop-in replacement for the IBM-standard
COM.SYS and VCOM.SYS drivers. They are NOT meant to be used with the
standard equipment drivers.
This release supercedes all previous releases. Copy the new files
over the existing files and reboot to activate the new drivers.
NEW IN RELEASE 3.23
*******************
* Added support for Quatech low-profile PCI serial adapters.
NEW IN RELEASE 3.22
*******************
* Added the "O" options flag for Quatech PCI adapters. If the command line
parameters for a Quatech PCI adapter include this flag, the driver will
not abort at boot time if the adapter is not present in the system. A
warning message will be displayed on the screen and will be posted to
the boot log file if logging is enabled.
A quiet version of this option can be selected by using "OQ". The
warning message associated with the "O" option will NOT be displayed
on the screen, but will still be posted to the boot log file.
See section 2.3.1 of the updated manual PDF for details.
NEW IN RELEASE 3.20
*******************
* Added the "/FT" option to accelerate RTS toggle-on-transmit operation.
See page 11 of the updated manual for details.
NEW IN RELEASE 3.12
*******************
* Eliminated a conflict with the IBM-standard COM.SYS driver that was
preventing coexistence with QCOM.SYS. This fix is intended for
customers having a compelling need to run both drivers. Quatech
continues to recommend that the IBM-standard drivers be replaced
by the Quatech driver set. Both QCOM.SYS and QVCOM.SYS changed in
this release, so be certain to update them both!
NEW IN RELEASE 3.11
*******************
* Fixed conflict with LANMSG$$ driver introduced by the "/D" option.
NEW IN RELEASE 3.10
*******************
* The "/M" option is removed. Delete it from the command line if you tried
it with the Release 3.03 code.
* Fixed memory locking conflicts with the OS/2 kernel.
NEW IN RELEASE 3.03
*******************
* "/M" option added to enable locking of all memory at boot time.
(Feature removed in 3.10.)
* Fixed bug where the Warp 4 Hardware Manager would inaccurately report
multiple instances of COM1 on systems where no COM1 was installed and
PCMCIA sockets were present.
NEW IN RELEASE 3.02
*******************
* More detailed error messages can be displayed during boot if for some
reason a port cannot be initialized.
* "/D" option added to enable logging of all on-screen messages to file
named QCOM.LOG in the root directory of the boot drive.
NEW IN RELEASE 3.01
*******************
* Driver will try to probe for actual presence of UART during boot time.
* Error messages during boot time if the driver doubts the presence of
an actual UART, or if the requested IRQ is not available.
NEW IN RELEASE 3.00
*******************
* OS/2 Resource Manager compliance
I/O and IRQ resources used by all serial ports controlled by QCOM.SYS
are registered with OS/2.
* High baud rates to 921,600 bits per second, depending on UART type.
* Support for 16750 UARTs and their 64-byte FIFOs.
* Address and IRQ masquerading for DOS and Windows sessions.
* Plug-and-play support for Quatech PCI serial adapters.
* Updated documentation
