[ale] quick way to raise DTR on serial port?

[christopher at bergeron.com (Christopher Bergeron)]

Does anyone know of a quick/simple/easy way I can raise the DTR signal 
on my serial port?  I'm trying to determine if the port is bad.

I can't seem to think of a way to do it with a bash script.  Is there a 
command I can send from within Minicom?  Or doe  anyone have a few lines 
of C or similar code that could do it?  Is there a gtk app that will let 
me toggle serial pins?

Anyone have any ideas?

Thanks in Advance!

P.S.
I'm at the console of the box, I'm not connected to a serial tty.
