Hi folks! I'm working on a project in which some of our clients will be using DOS PC's as their UNIX terminals. A requirement for some of our users is the ability to display more than the normal 24 or 25 lines on the screen. For certain parts of the system we would like to be able to display 40 to 50 lines on the screen. More than 80 columns is not necessary, and in fact we would prefer to have a 50-line by 80-column display. This would mean that the terminal emulator should be able to take advantage of alternate character-generation modes of the video adapter. (You can assume that all the PC's upon which this emulator will be used will have VGA boards and monitors. We have found that the 132-column emulators which use VGA graphics mode are difficult to read and are relatively slow. So we would be primarily interested in an emulator that used the higher-capacity character-based video modes.) Since this requirement extends to only certain users and screens of our system, we need to be able to programatically change from 25-line mode to 50-line mode and back again as needed with minimal disruption to was is already on the screen. PC Magazine recently had an issue that reveiwed many PC terminal emulators. Unfortunately, the article didn't address the capability of having more than 25 lines on the screen. Does anyone out there have any recommendations as to what terminal emulator might be suitable for our needs? Thanks. You may email me at marriott@grebyn.com. Chris Cobb, Software Engineer
