9 New Member
Hi all,

I am trying to get a certain amount of code in to my processor through the on chip UART. i hve developed a program to transmit data through the serial port COM1 but i m not able to direct the data into the chip. And in the echo mode of hyperterminal i m not able to recieve my data. Can any body help me out if i m missing something?

Thanx

Are you sure what your attempting is possible. Have you checked your processors documentation?

Hi Banfa,

Thanx for getting on with that.:-) I have throroughly checked in the documenst for that task and there is nothing missing with my side on the HandShaking Protocol though. However, the variables that i hve assigned writing to the port are simple i.e they are not Volatile. Does a Volatile Declaration of such variables make or break things?

Bye,
Sundarr

Where should I create my inherited class? Thank you

Hi, every 250 ms (timer event) I must send several commands via serial port. The serial unit will answer to each command sent. I must wait the answer before send the next command. How can I achieve this? I receive the incoming data in the "data received" event of the serial port. Furthermore I need to manage a timeout: if I receive no answer within a specified amount of time an event will be generated.

Hi all, I'm a newbie in .NET technology. I've already developed Serial communication applications in C++ (WIN32). And I wanted to migrate to .NET technology. There is a serial component in framework to read and write on serial port. I would like to make asynchronous reception. I saw that we can pass a delegate to the serial class which is call when some data is readen on the port.
