SUMMARY

Problems have been reported with garbage characters or with repainting in FoxPro for UNIX. Both situations described in this article have required tuning of the Digiboard software in some way.

MORE INFORMATION

Problem/Solution 1

A customer figured out how to stop getting garbage on the screen with a Wyse60 without running Digiboard's dscreen utility. In the gettydefs file on the 38400 line, the customer had CTSFLOW and -IXANY. The communications setup on the terminal setup (press F4 to get to communications setup) had the following settings: 

   Baud Rate=38400         DATA/STOP BITS=8/1
   RCV HNDSHAKE=XON/XOFF   XMT HNDSHAKE=XON/XOFF   XPC HNDSHAKE=OFF
The above setup worked with all applications except FoxPro for UNIX running at 38400. The customer found that by changing RCV HNDSHAKE=XON/XOFF to RCV HNDSHAKE=DTR, FoxPro would run correctly at 38400. The customer spoke to Digiboard about dscreen, but Digiboard did not know why FoxPro for UNIX would work with dscreen. The customer guessed that dscreen was slowing FoxPro for UNIX down enough to work correctly. The customer could not find any difference in the settings of the line while running dscreen and not running dscreen. Digiboard said dscreen does not do anything special concerning flow control.

Problem/Solution 2

Another customer was having a problem with screen repaints and screen colors in FoxPro for UNIX when using Digiboard's Doubleview. If the customer turned WRAPAROUND on, FoxPro for UNIX seemed to work correctly, but other applications, such as WordPerfect Office, would not work correctly with WRAPAROUND on.

In this situation, it's important to check the automargin ("am") terminfo capability. WRAPAROUND=ON is the same as "am"; WRAPAROUND=OFF is the same as "not am". To check this setting, you have to use the wpterm utility to look at WordPerfect's terminal facility as well as terminfo.

In this case, the customer looked in the wpterm program and edited the dbview and dbviewcol variables. The line "Can Automap be Disabled on this Terminal?" was set to N. This was right for WordPerfect 5.1 but it was set to Y for the WordPerfect Office setup. WordPerfect Office and WordPerfect 5.1 are supposed to use the same shared directories. WordPerfect Office mail was the program that was having problems the WRAPAROUND=ON setting in the Doubleview setup. To change the Automap setting, the customer ran the WordPerfect 5.0 wpterm program. The customer now has Doubleview set up with WRAPAROUND=ON, and the terminal now works correctly with WordPerfect Office mail and FoxPro for UNIX.
