SoftwareSerial resetting problem with Arduino uno
i have configured softwareserial port on uno (pin 2 rx , pin 3 tx) , connected usb port of pc through usb serial converter based on pl2303. connected build in usb port of uno same pc. have opened 2 terminal programs in pc connected both ports.
my sketch listens both hardware , software ports , if received on port reflected other port.
now if send uno's hardware port correct reflection uno's softwareserial port. if send character softwareserial port uno seems resets (i receives "hello" response both ports).
i tried experiment various baud rates , pin numbers softwareserial port. tried external power supply uno. still same resetting issue.

code: [select]
softwareserial softport(2, 3);
void setup()
{
serial.begin(9600);
while (!serial) {
}
softport.begin(9600);
softport.write("hello");
serial.write("hello");
}
void loop()
{
softport.listen();
if (softport.available() ) {
serial.write("3"); //this line never executed
serial.write(softport.read());
}
if (serial.available() ){
int value = serial.read();
softport.write(value);
serial.write(value);
}
delay(10);
}
remove softport.listen() call.
