Appendix D
Running the Controller Link Support Software under Windows 95
166
Precautions
If Windows 95 automatically writes data on the hard disk in the background or other applications are running under
Windows 95 during communications with a PC, communications errors (such as
“
Wrong network type
”
) may oc-
cur. In particular, when a Host Link port is used, communications errors are more likely to occur depending on the
communications protocol being used.
If such communications errors occur, the frequency of error occurrence can be reduced by changing the perfor-
mance or reception buffer performance for communications port settings on the Control Panel.
Setting Delayed Writing for Drives
Set delayed writing for drives under the file system settings for system performance on the Control Panel.
Setting the Reception Buffer for the Communications Port
Reduce the current reception buffer size under the communications port settings for the device manager for sys-
tem settings on the Control Panel.
If communications errors recur even after the above settings have been changed, close other applications running
under Windows 95.
Note 1. If the same problem occurs even after the settings have been changed, run the Controller Link Support
Software in DOS mode.
2. For computers with Windows Keys, never press a Windows Key during online connection with a PC.
Otherwise, the line may be disconnected or Windows 95 may hang up.
3. Never switch to another application by pressing the Escape or Tab Key while holding down the Alt Key.
Otherwise, the line may be disconnected or Windows 95 may hang up.
4. If an echoback test is to be executed, always execute it in DOS mode. Otherwise, the correct test results
may not be obtained.
Computers with Infrared Port Communications
In the Controller Link Support Software, the serial port must be enabled.
If you are using an infrared port, disable it or set the serial and infrared ports so that they do not overlap.
