SCO xenix mscreen help required

[abl]

I have been trying to use the SCO Xenix mscreen program  which  gives  the
possibility   of  having  multiple  logins  on  one  tty.   I  have  setup
/etc/mscreencap with a simple set of definitions and enabled a  couple  of
ttyp* slave devices.  The master devices exist.

When I go into mscreen I get the help messages and then a new login prompt
and  can  login  however  I am not able to give mscreen commands to change
screen or get help etc.

I have setup simple inputstrings like Escape 1 (\E1) to change windows.

I use SCO 386 Xenix 2.3.1. mscreen size is 17904, date Jul 14 1988.

Anybody know what I am doing wrong (please)?
