### Timeouts
* If a single packet takes more than 2 sec to transmit (1 sec on 2v25) Espruino will send `NAK` and will return to normal REPL mode.
* If there's more than a 10 sec gap between DATA transfers for a file, Espruino will automatically close the transfer and the file. Subsequent DATA packets will be `NAK`ed as no file is open.
### Example ### Example
As an example, to create a file named `hello.txt` with the content `Hello World`, the packet is constructed as follows: As an example, to create a file named `hello.txt` with the content `Hello World`, the packet is constructed as follows:
