Dear Phil,
I replaced thye dataReceived function by stringReceived, and ran the code.
But when I do this, the program does not even enter the stringReceived function.
I also tried a modified version of the programs above with LineReceived
protcol, and here too I have the same problem of fragmented data from the
dataReceived function.
Thanks.
Siva.
