// This example shows how to buffer writes to a stream.
|
||
|
|
//
|
||
|
|
// Like "echo," it reads from the serial port and prints back the same thing.
|
||
|
|
// What's interesting with this program is that it writes in chunks of
|
||
|
|
// 8 bytes, even if it seems to write them one by one.
|
||
|
|
//
|
||
|
|
// As you'll see, you need to type at least 8 bytes to see something. That's
|
||
|
|
// because it waits for the buffered to be full before sending it to the serial.

// written in chunks of 8 bytes.
