4 TroubleshootingListed below are some tips that can be consulted in the event of difficulties. Consultingthis information may make calling for technical support unnecessary.{ Ensure that the Interrupt Status Register on a Quatech serial adapter is enabled. Allproducts ship from our factory with this register enabled. This is done using a jumper orswitch on ISA or PCI adapters. PCMCIA adapters will have this register enabled unlessyou have disabled it with a command line option on the adapter’s PCMCIA client devicedriver. Refer to the User’s Manual that came with your serial adapter for details on how tocheck the Interrupt Status Register setting and enable it if necessary.{ Any ports that cannot be installed will cause a failure message for that particular port to bedisplayed during system boot. Other ports will still operate. Such a failure is usuallycaused by some other device already claiming the IRQ the port is attempting to use.{ The CONFIG.SYS file "DEVICE=" statements for the QCOM.SYS and QVCOM.SYSdrivers should occur after the "DEVICE=" statement for MOUSE.SYS if a serial mouse isbeing used. This is because the mouse driver must take complete control of its serial portand cannot do so if QCOM/QVCOM has already claimed the port.{ All serial ports must have parameter sets specified on the QCOM.SYS statement inCONFIG.SYS. The standard IBM drivers will install COM1 and COM2 by default. TheQuatech drivers will not install any ports by default.{ DOS applications may need custom configuration in order to use serial ports atnonstandard addresses. There is typically a configuration file or menu that can be used toaccomplish this. Configurations typically expected by DOS applications are:COM1: 3f8 hex, IRQ4 COM2: 2f8 hex, IRQ3COM3: 3e8 hex, IRQ4 COM4: 2e8 hex, IRQ3{ This driver set supports serial ports named "COM1" through "COM32". Multiportadapters should be installed such that all ports fall within this range. Ports outside thisrange are not usable.{ The enhanced SERIAL.PDR spooler module is no longer supported by Quatech.{ The device driver requires OS/2 2.11 or later.{ At the time of release, this device driver contains no known bugs or errors. Any problemsthat arise will be addressed by the Quatech Technical Support Department. If a TRAPoccurs and the fatal dump screen indicates that the offending code is in the "COMxx" or"QTCOM$" driver, copy ALL of the information from the screen and be prepared tosupply it to the technical support personnel. The fatal dump information can often rapidlypinpoint a problem.Quatech Asynchronous Serial Device Driver for OS/2 19 |
