Need UNIX Termcap for PC/AT Keyboard

[Unisys]

We are using an IBM PC/AT as a SunOS terminal.  The PC is running IBM's
Screen Reader to provide voice output to a blind user.  It appears that
the VT100 emulation in our LAN package is interfering with the Screen
Reader.  We're  looking for a UNIX termcap file entry for the PC/AT keyboard
(which should allow me to eliminate the terminal emulator).  Please help.
