I, too, wanted something like this.  Having no source code for
uugetty, and not wanting to re-invent that wheel, I did the following:

Write a new program that takes exactly the same command line
arguments as getty, plus another one (I used -A) specifying a file
to be copied out to the tty port.  This program simply opens the tty
port as stdin, stdout, and stderr, writes out the content of the
initialization file (containing AT commands) and then spawns the
real uugetty (or getty) program.  The original uugetty remains
unchanged, and the inittab file is edited to respawn my pre-getty
program on each modem line.
