A test of the poll() and select() APIs using FIFOs and, if available,
stdin, and a TCP/IP socket. This example also includes a nice select
based TCP/IP server example.
based TCP/IP server example. In order to build this test, you must the
following selected in your NuttX configuration file:
CONFIG_NFILE_DESCRIPTORS - Defined to be greater than 0
CONFIG_DISABLE_POLL - NOT defined
In order to use the TCP/IP select test, you have also the following
additional things selected in your NuttX configuration file:
CONFIG_NET - Defined for general network support
CONFIG_NET_TCP - Defined for TCP/IP support
CONFIG_NSOCKET_DESCRIPTORS - Defined to be greater than 0
CONFIG_NET_NTCP_READAHEAD_BUFFERS - Defined to be greater than zero
In additional to the target device-side example, there is also
a host-side application in this directory. It can be compiled under
Linux or Cygwin as follows:
cd examples/usbserial
make -f Makefile.host TOPDIR=../../. TARGETIP=<target-ip>
Where <target-ip> is the IP address of your target board.
This will generate a small program called 'host'. Usage:
1. Build the examples/poll target program with TCP/IP poll support
and start the target.
3. Then start the host application:
./host
The host and target will exchange are variety of small messages. Each
message sent from the host should cause the select to return in target.
The target example should read the small message and send it back to
the host. The host should then receive the echo'ed message.

Send only large, multi-packet messages. Default: Send large and small.

This will generate a small program called 'host'. Usage:
1. Build the examples/usbserial target program and start the target.
2. Wait a bit, then do enter:
dmesg
At the end of the dmesg output, you should see the the seria
device was successfully idenfied and assigned to a tty device,
probably /dev/ttyUSB0.
3. Then start the host application:
./host [<tty-dev>]
Where:
<tty-dev> is the USB TTY device to use. The default is /dev/ttyUSB0.
The host and target will exchange are variety of very small and very large
serial messages.
