Appendix C: Error Messages

Normally, during the course of operations, error messages may be displayed on the

screen. The error message is usually self explanatory and is caused by such things

as a printer running out of paper or a modem not being connected, etc. The error

message will usually suggest or infer what action is required to correct the situation.

After any type of Run Time Error, DLS-1 should be restarted. If an error message is

generated and you are unable to correct the error it could be due to a hardware

compatibility problem or not enough conventional memory. Refer to Appendix D and

Appendix E for Computer Compatibility and Modem information, and Section 1.1.4

for Memory Requirements.

Appendix D: Computer Compatibility

The DLS-1 software was designed to run on an IBM PC XT, AT, 386, 486 or higher

true

compatible. Not all computers that claim compatibility with IBM are actually

100% compatible. If you suspect that your computer is not 100% compatible we

suggest you contact the supplier of your computer.

Due to the variety of Compatible computers available we cannot tell you specifically

what can (if anything) be done to correct a compatibility problem. The following are

typical items that could improve or help.

1 Make sure you are using a current version of MS-DOS. DOS ver 5.0 or greater is

recommended.

The DLS-1 Software is not compatible with Microsoft Windows.

2 Make sure your computer is configured properly. The XT uses dip switches on the

motherboard and the AT uses a setup/diagnostic program. Consult your computer's

operations manual for specific information on setting up your computer.

3 Some memory resident programs may conflict with the DLS-1 software. If you are

experiencing problems, try running your computer without them active. Refer to the

owner’s manual of the memory resident program to determine how to disable it.

4 The hardware installed in the expansion slots of your computer could be causing

a conflict with the serial channel or modem that the DLS-1 software is trying to use.

If you are using an internal modem, set it for COM2 and make sure no other

hardware is selected on COM2. If you are using an external modem, make sure

the serial port it is connected to is working properly. NOTE: If the modem is

connected to COM 1, there should not be a serial device connected to COM 3 (and

vice versa). The same is true for COM 2 and COM4: if the modem is connected to

COM 2, there should not be a serial device connected to COM 4, and vice versa.

The Norton Utilities - Norton Cache

To improve file access speed, it is suggested that you use a cache program, such as

Norton Cache. Cache programs set aside a portion of memory in your computer for

the temporary storage of files. By accessing these files in memory rather than having

to retrieve them from a disk drive, the computer’s speed and performance is

improved. Minimum system requirements for Norton Cache are: DOS 3.0 or higher

and 256 K of conventional memory. Contact your computer or software dealer for

more information.
