serial Read/ Write Synchronisation


Recommended Posts

Is a sequence structure the best to ensure a serial read/write between two pc's does not get mixed up?

PC1 will send to PC 2

PC2 does something with the data and sends back to PC1

so

PC1 PC2

Write --> Read

Read <-- Write

Do i need ad a delay anywhere in the loops to ensure synchronisation??

or am i going down the wrong track al together??

Also, as part of the read, i have a concenate string function. It only write to the serial when the string is complete. Once its complete, the string is written to serial port and then i want to move onto the next sequence in the structure.

How to terminate a while loop when the string is written??

Regards

Jason
