Do we can enable/disable RS232C connection on
windows xp PC.One of my software seem cannot
detect some devices connected via RS232C
connection.

What might cause this problem?Any ideas?

Sometimes I need to enable and disable additional
of usb to my pc.I know that the first step is type
'regedit' on start ==> run... but don't know the next step.
Would somebody like to help how to done the next
step.I work with windows xp.
