A General Overview of the 3270 PC PSS ID Number: Q33558 Article last modified on 09-19-1991 PSS database name: PSS

Summary:

The IBM 3270 PC is an 8088-based machine that was designed to bridge the gap between the PC and IBM mainframes. It can run several mainframe sessions and one DOS session concurrently through the 3270 PC Control Program. The control program uses window-like features to switch between sessions and the PC program. One feature that is particularly useful is the ability to “capture” screens of data from a PC or mainframe session and copy it to any mainframe session.

The graphics adapter has the two CGA modes of 320x200 with four colors and 640x200 with two colors; it also has modes only supported by the APA (All Points Addressable) graphics adapter that comes standard in the machine. The two extra modes are 720x350 with two colors and 360x350 with four colors.

The keyboard has 39 additional keys for dedicated 3270 functions. Many of the keys may not be usable with PC programs because key codes for many of them may not match those of their PC counterparts.
