Serial FIFO Test Program
------------------------
"fifotest" is a test program for checking the integrity of the serial port
FIFOs.
Features:
- Opens and closes the serial port for each message,
- Sends variable length messages,
- Consumes received messages partly (the remainder is supposed to be
flushed),
- Data is generated randomly, using a seed for reproducability (seed zero
means pseudo-random),
- Received data is verified against the expected data
Usage:
fifotest: [options] <txdev> <rxdev>
Valid options are:
-h, --help Display this usage information
-i, --seed Initial seed (zero is pseudorandom)
-l, --len Maximum message length (default 1024, must be <= 4096)
-n Number of messages to send (default zero is unlimited)
-s, --speed Serial speed
-v, --verbose Enable verbose mode
The first device specified is used for output, the second device is used
for input.
Examples:
* Transmitting from ttyS0 to ttyS1:
fifotest /dev/ttyS0 /dev/ttyS1 -s 1000000 -n 10
Wiring:
TXD0 -> RXD1
