I posted the following question to comp.unix.wizards without any definitive
response.  Can anybody here offer some assistance.

I'd like to know if there is a way to be able to find out (in software) if 
a peripheral is powered up.  Is there a generalized, high level way to inquire 
(and set) the DTR signal on an RS-232 connection?  

				       thanks in advance
