I.6 Some Notes on System Resources
COM Ports and Interrupts
PC208W is capable of running in the background while you are doing other
work with other programs. To do this, it uses the system’s idle time for some
of its serial communications. Some other applications may be so resource
intensive that PC208W does not receive sufficient time for its communications.
PC208W will not run reliably with these applications loaded.
The Windows environment provides access to the COM ports via a COM port
driver. Many computers have COM ports which share interrupts with other
COM ports. (Typically COM1 and COM3 share IRQ 4 and COM2 and COM4
share IRQ 3.) This can be checked by examining the ‘Ports’
(Settings/Advanced) setting in the Windows Control Panel. A COM port
sharing an interrupt with another device can prevent Windows from reliably
performing communications using that port, particularly if the COM port and
device are used concurrently. This shared interrupt problem would also affect
operation of PC208W.
If you appear to be experiencing communication problems when
using external modules, always check the COM ports setting in
the Windows Control Panel, using the ‘Ports’
(Settings/Advanced) option, and check for any shared interrupts.
Other programs may also try to use the COM ports, and some may leave the
COM ports “ open” even when not active. This is especially true of DOS
based communications programs. If PC208W has trouble connecting to a
datalogger when you believe the setup and connections are correct, check to
make sure other programs that use the same COM ports are closed.
For Windows 3.1 and 95 Users
A problem which is inherent to Windows 3.1 and 95 may surface when
scheduling Tasks which call DOS programs. When a DOS command is
executed, a certain amount of system resources are allocated to this command.
Windows 95 does not free up this resource when the command has been
executed and control is returned to Windows. This memory is freed, however,
once your computer system is rebooted.
