Pseudo-ttys and hft's

Hi,
I have a 6150 running AIX 2.2.1.
I have written a program which uses pseudo ttys to interface to a net
much the same as telnet does. I sit on the master side of the pty and regular
applications, i.e. sh vi etc., sit on the other.
sh
--------
| pts |
| ------ | pseudo-tty
| ptc |
--------
my prog

the wire
My problem is: when I start up
vi or pg or the like, someone writes " ESC [ x ......." on the data stream.
I have discovered that this is a hft ( High Function Terminal ) ioctl
call which gets thrown on the data stream if the device is a pseudo tty. But how
did it get there, (did vi write it ?), and how do I stop it. Do I have to
inspect the whole data stream and strip out hft calls?
Help.
