connecting to sony ericcson with hyperterminal
As i recall in previous topics, n6610 family do need with a driver. I dont know for sure because i havent tried it myself. For your sony ericson, if your cable is a RS 232 connector, which you can directly connect to your serial port you don't need a driver. But if it is a USB type connector, which I think it is, you will need a driver.
A general rule, you will need a driver only to connect a DCE(digital communication equipmnet), your phone for example, if its physical connection to the hyperterminal is not RS 232. USB for example. The driver will take care of making virtual COM port for your USB connection. In my case I connected my phone to Host via Bluetooth dongle. The bluetooth driver takes care of providing a virtual COM port.
