ttynvt makes a virtual serial device (tty) and connects

1 Build environment
gcc is required.
glibc must support pthreads.
libfuse - Filesystem in Userspace - development support is needed.
2 Target
The linux kernel at the target system must support FUSE (FUSE_FS=y) and
libpthread and libfuse must be installed in the root filesystem.
3 Build
$ autoreconf -vif
Example configuration for native build:
$ ./configure
Example configuration for cross build:
$ ./configure --host=ARCH-unknown-linux \
CC=PATH-TO-CROSS-GCC \
PKG_CONFIG_LIBDIR=PATH-TO-CROSS-PKG_CONFIG_LIBDIR"
or
$ ./configure --host=ARCH-unknown-linux \
CC=PATH-TO-CROSS-GCC \
LDFLAGS="-L PATH-TO-LOCATION-OF-libfuse.so"
$ make
The default target in the Makefile builds the Network Virtual Terminal.
Output name is: ttynvt.
4 Run
The application (ttynvt) installs a virtual serial device in the /dev
directory (by default: /dev/ttyNVT0).
The major/minor number of the device, the address (name/IP) and the port
number of the serial server must be specified when the application
is started (command-line options).
E.g.
./ttynvt -M 199 -m 6 -n ttyNVT0 -S 169.254.1.1:5020
To get a list of all command-line options:
./ttynvt --help
5. Test
The serial server: ser2net (http://ser2net.sourceforge.net/) might be used
to test the virtual serial server on the target.
Install the server (ser2net) and add following line to the configuration
file (/etc/ser2net.conf):
5020:telnet:0:/dev/ttyS0:115200 remctl NONE 1STOPBIT 8DATABITS RTSCTS HANGUP_WHEN_DONE
At the server, plug-in a loopback connector in the serial port (ttyS0).
At the target, open the virtual serial port, with a termial program,
e.g minicom:
minicom -D /dev/ttyNVT0
6 Diagnostic
Add the command-line option '-D <level>' to enable logging of diagnostic information.
The log is forwarded to syslog with the debug level.
Wireshark is also very useful when debugging the interface between the client
and the server.
