Write this routine if you want to use a terminal not supported by TSO/VTAM. IKTCAS23 calls IKTINX1, if provided, when a logon request is encountered from a terminal other than an IBM® 3270, 3767, or 3770. (If TSO/VTAM is used with NTO, the 2741, WTTY, and TWX Models 33 and 35 are also supported.) IKTINX1 must verify that the terminal is supported by user-written routines (that is, a terminal input manager, a terminal output manager, and edit routine IKTGETXT), and it must provide the terminal type of X'03', the buffer size, and the device bind image.
