i wonder what problem you are trying to solve with this.

you did not specify your problem and yet you say that
you "want to use the command" so you are giving
a possible solution to yet unknown problem.

do you simply want to display a DOS program on startup?
then you might as well boot windows and place
the DOS program into the startup folder.

anyway, you can only start a screen session
on a terminal which belongs to the user, too.

example:

  guckes@home:~> id
  uid=1000(guckes) gid=1000(guckes) groups=1000(guckes)

so i am "me" on my home system.

i'll use "sudo" to become "root".

  guckes@home:~> sudo bash
  Password:
  2.05b root@home ~> id
  uid=0(root) gid=0(root) groups=0(root)

but the terminal still belongs to user "guckes":

  2.05b root@home ~> ls -l `tty`
  crw-------    1 guckes   tty      136,   5 Mar 18 13:18 /dev/pts/5

so that's why starting screen as root won't work.

but i think there was a way... gotta read
up on the mailing list archive for that..

then again, i haven't used dosemu in quite a while.
i think you have to make sure that DOS is installed
on your disk - and maybe answer some prompts, too.

anyway, i think you should a decription of your *real* problem
which you are trying to solve with the help of screen and dosemu..
