I have built a stand alone sequencer (2.0.11) application, something

that is intended to be launched, run once and exit. I launch the program

with the -s option to create an iocsh.

The program runs and operates as expected but after the program exits

the behavior of the x-terminal from which the program was launched is

altered. For example, pressing the 'enter' generates a new prompt but

without a line-feed. If I type "reset" at the x-terminal command prompt

I can restore normal operation of the x-terminal.

The final state of the program is:

    state finish {
	    entry {
            ps_enable = 0;
            pvPut( ps_enable, SYNC);
	    printf("rampTiSp cleanup\n");
         }
         when(delay(2)) {
            exit(0);
	 } state finish
    }

There are two state sets.

Is there a better way to exit the program?

Thanks,
