Hello everyone,

I am currently facing this problem:
I have an external RFID device which is connected to my Handheld
device. Currently I power it using a Hyperterminal application (source
code not provided by author) Communication after that via serial port
is not a problem.

However, now i am tasked to power up this RFID device solely through my
C# application. I have no idea how to start doing this. Anyone has any
ideas?

Thanks!
 
Sounds like it's powered when it receives serial data. Create a SerialPort
instance and send it data.

No it isn't.
I have to launch a Hyperterminal application provided by the device
vendor to power up the RFID device before running my C# application to
send and recieve serial data.

Now i have to integrate this powering up portion into my C# application
 
Ok, so how do they power it up? There's no standard PowerUpMyRFIDDevice
API, so unless the OEM tells you or provides an SDK, we can't really help
you out.

What's a "Hyperterminal application"? Hyperterminal is provided by MS.
It's a script file that you send the device via Hyperterminal? If so, read
that and figure out what it does. Frankly, though, if the device vendor
won't tell you how to use it, it's time to find a new vendor!
