Plotter appears to not be doing flow control.

Question:

I have a Plotter that appears to be doing no flow control.  Could you
help me set this up?


Response:

Checked Plotter manual and found it is only capable of Xon/Xoff flow
control.  Went into smit and turned off DTR flow control.  Added a
virtual printer as "PLOTTER" and sent a job.  It printed with no
problems.

Response:

He upgraded to 3.2.4 and now he can't plot at all.  We lowered the baud rate
to 2400bps and now he can plot, so it appears to be a timing problem.  

Found that in 3.2.4 the trigger value for responding to interrupt characters
was increased from 0.  Therefore, the system will get characters from a tty
device but not respond immediately.  I had him change the trigger value to 
0(zero) '/usr/lbin/tty/stty-rs rtrig 0 \
