Can we copy a data from memory to a port and then read it in RCM4000?

Your question is not very clear. Please rephrase it. Are you talking about a serial port or a parallel port or do you want to send something via a TCP connection?

It is about parallel ports.

You should be able to do it programmatically. Are you looking to store 1’s and 0’s into memory and send them out a parallel port? If so, you should be able to do it with C code.

I want to send the data from a memory location inside RCM4000 to the parallel ports.
