When I submit
# qrsh -l h=<host> -pty yes sleep 1000
from a sol-sparc64 host:

SGE 6.2u3, exec host is sol-sparc64:
- Press Ctrl-Z ->
  - ^Z is printed locally
  - no local prompt
  - sleep process is still in state "S"
- Then press Ctrl-C ->
  - get local prompt
  - sleep process vanishes

SGE 6.2u3, exec host is lx24-amd64 (Red Hat Enterprise Linux 3):
- Press Ctrl-Z ->
  - no ^Z is printed
  - no local prompt
  - slep process is in state "T"
- Then press Ctrl-C ->
  - nothing happens

Both should behave like on lx24-amd64 - the ^Z must be forwarded to the remote pty and be interpreted there, i.e. the currently running
process must be suspended.
