WordPerfect® 6.0 for DOS

Problem

Are their any general trouble shooting steps that can be used to check for problems WordPerfect with MainFrame Terminal Emulators?

Answer:

Checking Conventional Memory is perhaps the best starting point. Listed below are some other steps that may be tried. They are:

1. Load the emulator (if it isn't already loaded).
2. Type MEM and press Enter at the DOS prompt. Look for the largest executable program size. If the number is below 550K, examine the CONFIG.SYS and AUTOEXEC.BAT files for TSRs and drivers that could be loaded high.
3. Try loading everything high. The CONFIG.SYS file should normally be set up in the following order:
DEVICE=HIMEM.SYS
DEVICE=EMM386.EXE NOEMS (or amount of EMS in K, RAM)
DOS=HIGH,UMB
FILES=65
BUFFERS=10,0
4. Try arranging the drivers or TSRs being loaded in order from largest to smallest.
5. If conventional memory cannot be brought up to 550K, try running in Text mode and turn off screen features such as Scroll Bars, Borders, Ribbon, Button Bar, etc.
6. if the emulator is bigger than approximately 100K, it probably won't work at all. One emulator available is 140K to 160K, depending on configuration, and it must be in conventional memory to work. With MS DOS 5.0 or 6.0, you can have up to 615K free conventional memory (615K = 629,760 bytes). The problem with memory is as follows:
615K - 140K = 475K
475K isn't enough memory for WP 6.0 to function.

Startup Options
Terminal Emulator problems can often be solved with common startup options. Thinking logically will help you determine which options to use. Don't guess! Here are some suggestions for startup options. Try them one at a time in the order given.

1. Emulators look at the keyboard for hotkey activation. Try the options /NC/ND/NK/NO all together. If that works, try the options one at a time. Try to eliminate /NK if possible, since it disables the enhanced keyboard calls.
2. Emulators sometimes use Expanded memory, so try /32. If that fails, try /DU, then /NE.
3. Try /NX.
4. If the problem occurs when printing, try /NH.
5. If nothing has worked up to this point, try the following line all at once. Then, eliminate the options one at a time, testing to see that it still works.
/32/DU/NC/ND/NF/NH/NK/NO/NP
6. Try /DL as a final resort.
