SUMMARY: Low level (?) error "Error int getting (TCGETA) tty params" executing scripts remotely with SSH and sudo

As usual we quickly got quick and interesting proposals.

Two were axed around assumptions about terminal types and proposed the ssh
switches -n and -t.

I was able to test -n which didn't work just trying (didn't read the man on
ssh)

ssh -n mmsgui@mpm sudo /opt/MPMServer/bin/MPMGuiIhm -c status

I also got some proposals to insert " and \" but I wasn't successful before
the solution (below) came.

Didn't have time to try everything before our programmers modified the source
program MPMGuiIhm.

Apparently there was a call to ioctl.h to get terminal parameters in that
program. When the call was removed it worked.

Unfortunately my summary could be a more complete regarding the switches, but
unfortunately I don't have more elements.
