Hello!
Either you google after an interface if you wish to construct it 
yourself or you buy one. MicroHam builds a few good interfaces that 
combines both RTTY and CW (including PTT). Check their website and they 
also have a US distributor. Most of their interfaces uses the USB-port 
which is really good since many laptops aren't even equipped any longer 
with a COM or printer ports.

Hope you find what you are looking for.
