Set the "standard" number of screen rows.
TN3270
For TN3270 applications, 24 is recommended for standard rows.
TN5250, TNVT
For 5250 and many TNVT connections, this should be 25, to accommodate an additional status line. For Windows/2000 and Windows/XP TelNet servers, 25 is needed to avoid unnecessary scrolling.
