Of course, you always have a voltage on every line.  It's the value of that
voltage that matters.  Your statement is like saying "I have weather in my
back yard".

There is no clock line if you're using the USART in the normal UART mode,
such as when communicating to a PC COM port.  That's what the "A" in UART
means.

It really sounds like you're using the hardware in UART mode.  The two pins
you should be looking at are serial transmit and serial receive.  They have
different names on different PICs.  If you had mentioned what PIC you are
using (didn't it occur to you this might be useful information?) I could be
more specific.
