Receive of data and transmission at different speeds

SoftwareSerial hx1Serial = SoftwareSerial(2, 3);

void setup() {

  Serial.begin(9600);
  sendSerial.begin(2400);
}

void loop() {
  data=Serial.read();
  sendSerial.print(data, BYTE);

maybe can referred for example. ?

While it works in principle, it can have big time trouble because the 9600 baud loop can be receiving characters at 4X the rate the 1200 baud loop can send them out, and the Serial library only holds a small buffer so most likely would lose characters if continuous 9600 loop characters were coming in.

Lefty

reacyve data like cycle, if send one of the four cycles for example if the data split / 4 and send the data speed of 2400? and transmission of 1 cycle of 4?
