thank you

In order to communicate serially between PDA and hyperterminal, you can use vb.net and make use of the Serialport class available under the namespace 

System.IO.Ports.

its not mandatory to use device manager, you can refer to the code below in c# for serial communication b/w PDA and hyperterminal with out use of device manager.

Regarding the cable as you are making use of serial communication, rs232 or sync cable should be good enough.
