## SoftwareSerial: peek

#### Description

Return a character that was received on the RX pin of the software serial port. Unlike read(), however, subsequent calls to this function will return the same character.

Note that only one SoftwareSerial instance can receive incoming data at a time (select which one with the listen() function).

#### Parameters

none

#### Returns

the character read, or -1 if none is available

#### Example

SoftwareSerial mySerial(10,11);
void setup()
{
mySerial.begin(9600);
}
void loop()
{
char c = mySerial.peek();
}
[Get Code]
