Appendix B. Troubleshooting
By using the supplied serial utility diskette and following these simple steps, most common problems can be eliminated.
1)Identify all I/O adapters currently installed in your system. This includes your onboard serial ports, controller cards, and sound cards. The I/O address used by these adapters, as well as the IRQ (if any) should be identified.
2)Configure your serial interface so that there is no conflict with currently installed adapters. No two adapters can occupy the same I/O address.
3)Make sure the Serial Interface is using a unique IRQ. While the Interface does allow the sharing of IRQs, many other adapters (such as SCSI adapters and onboard serial ports) do not. The IRQ is typically selected via an onboard header block. Refer to Chapters 3 and 4 for help in choosing an I/O address and IRQ.
4)Make sure the Four Port
5)Use the supplied diskette and this manual to verify that the Serial Interface is configured correctly. The supplied diskette contains a diagnostic program (SSD) that will verify if an adapter is configured properly. This diagnostic program is written with the user in mind and is easy to use. Refer to the README file on the diskette for detailed instructions on how to use the SSD program.
6)These are know I/O conflicts:
•The 278 and 378 settings may conflict with your printer I/O adapter.
•3B0 cannot be used if a monochrome adapter is installed.
