SCO Com Port not Responding
SCO Com Port not responding is a message usually displayed when the system cannot access hardware devices connected on the SCO com port. This could be modems and other networking devices that use this port. Once this message is displayed, getting the devices to work could be a tiresome task if the right diagnosis is not made.
The first thing to check is whether the relevant SCO Com drivers are up to date. Drivers ensure that the virtual communication between the system and other physical devices flows well. Malfunctioning drivers or those that have been altered with hinder efficient contact and communication between devices.
On modems, the SCO com port not responding message is usually seen when the modem cannot be accessed by the system. Persistent trials at accessing it may lead to processor overwork and the consequent system ‘freezing’. Any user command at such a time especially using the mouse gives back the same non-responsive message. The only thing that the user can do to reboot the system is use the task manager to shutdown the non responding program. Some users claim that particular products such as Digi board modems have problems working with the SCO com port. To check if this is the case, the user should check the for background processes that may be running on the SCO port.
Viruses could also be another cause of the SCO Com port not responding message. Like all Malware does, it affects the file registry and alters the codes of software running in the system. If the drivers of the SCO com port have been affected, any attempt to access the devices connected to the system will yield the non-responsive message. If one is using different applications that use the SCO port, the same problem may be appear. This is because the applications all compete for the same attention from the port. The processor has to take turns accessing the resources needed for the performance of each application.
The SCO Com port not responding message may also be seen where the programming errors affect the ports therefore interfering with their performance. In other cases, a trigger from the user can send programs that use the SCO com port can send the program in an endless loop. When the system fails to respond to all the spin of demands being placed on the processor, then the machine hangs and displays the message indicating that the port is not responding.
