@ jeeson
for checking serial port simple short TX and RX pin of port
these are 2 and 3 pins of port
when these pins will shorted then the data you will send on com port that will be returned to the pc
you can use any software to check like hyper terminal, terminal ,putty etc

for parallel port connect led's on data pins and send some data on port some led's will glow some will off depend on the binary of parallel port

What port addresses are you using. ?
Most Windows operating systems block direct access to parallel ports, have you allowed for that?
