ATT50.COM will switch the ATT monochrome display from 25 lines to 50 by changing
to super high resolution mode while ATT25.COM will switch back to the 25 line
mode.

Will work with DOS commands DIR and TYPE. Most other programs will require
special drivers to run in 50 line mode. 123 v2.0 and REFLEX 1.1 are the only
two I know about where drivers have been provided. Will not work if you have
ANSI.SYS in your CONGIG.SYS file or with other programs providing their own
version of ANSI such as DESKVIEW.
