Serial Read/Write Test Program
------------------------------
"sercat" is a test program for reading from or writing to a serial port.
It allows to configure baud rate and hardware flow control in one shot,
without using e.g. stty.
Usage:
sercat: [options] <dev>
Valid options are:
-h, --help Display this usage information
-f, --hwflow Enable hardware flow control (RTS/CTS)
-n, --noflow Disable hardware flow control
-r, --read Read mode (default)
-s, --speed Serial speed
-v, --verbose Enable verbose mode
-w, --write Write mode
Examples:
* Send a short message to ttyS0, using hardware flow control:
echo Hello | sercat --write --hwflow /dev/ttyS0
* Read a message from ttyS0:
sercat /dev/ttyS0
