I am working on a semi-auto detection idea for Arduino for the Scope project.
It does require a little user intervention but minimal.
It works by just responding to two on screen prompts to unplug and plug Arduino

There are two versions and both work perfectly well and give... (3 Replies)

Waiting for more fun Ardunio parts from AliExpress, I decided to test two cheap Chinese Arduino UNO clones.
The Arduino UNO R3 (CH340G) MEGA328P
The Wavgat UNO R3 (CH340G) MEGA328P
Both of these Chinese Ardunio clones sell for about $3 USD, delivered to your door.

Just finished a quick Python script to send the current unix time over to the Arduino from macOS, so in the absence of GPS or some other way to get the unix timestamp (epoch time) to the Arduino, I can get my macOS and Arduino UNO synced to within a second.

My favorite projects are always related to the "latest" tech in command and control, networking and network communications. This Elecrow GSM/GPRS/EDGE SIM5360E 3G Shield seems to be the "latest and the greatest" as far as 3G and GPS, as far as I can see so far, but I has it drawbacks for sure.... (6 Replies)
Today I received my NB-IoT Arduino Shield for AIS (Thailand). Here is a "pinout" photo of the shield.

cyclades-ser-cli
cyclades-ser-cli(8)cyclades-ser-cli(8)NAME
cyclades-ser-cli Serial Port Interface for Cyclades Terminal Servers
SYNOPSIS
cyclades-ser-cli [options] devname rasname physport
DESCRIPTION
The cyclades-ser-cli program connects a Unix device file 'devname' to a physical port 'physport' of a Cyclades Terminal Server 'rasname'.
cyclades-ser-cli provides the I/O interface between the device file and the physical port, running as an 'user-mode device driver'.
If 'physport' is assigned to 0, then 'rasname' is used as the IP address on an IP-based serial port addressing.
OPTIONS
cyclades-ser-cli may be started with the following options:
-u ptyiosize
Sets the internal device I/O size to ptyiosize (maximum 4096 bytes, default 1024 bytes)
-n netiosize
Sets the internal socket I/O size to netiosize (maximum 512 bytes, default 128 bytes)
-i retrydelay
Delay in seconds between connection requests (default: 60)
-r retries
Number of connection request retries before exiting. (default: infinity)
-s Use the Socket Server protocol for talking to the server, this means just piping all the data down a TCP connection with no control
information, so it's impossible to change the port speed etc. The default is to use the RFC2217 protocol.
-m modem handling
The default is 0 which means to check DCD state, 1 means to ignore DCD.
-c close mode
Last close handling; the default is 0 which means to hangup the modem, 1 means not to hangup.
-p start port
TCP base port of servers at terminal server side (defaults: 31000 for Socket server, 30000 for Remote Telnet Server). Note: if
'physport' is assigned to zero, this option has no effect, the Telnet Server standard port (23) is used.
-d debug level
The default is debug level 0 (little debugging), level 1 debugs internal state changes, level 2 debugs events, and level 3 debugs IO
calls.
-f Run in foreground, this is suitable for running from init.
-x Console mode: normally all messages are sent to syslogd (using local2 facility). With this option, all messages will be sent to std-
out and cyclades-ser-cli runs in the foreground. This implies -f
USE
Every instance of cyclades-ser-cli will have a virtual serial device which is a sym-link to a pseudo-tty. A terminal program can then talk
to the virtual serial device and it's data transfers will be redirected across the network. Each virtual serial device will be accompanied
by a Unix domain socket with the same name with the addition of ".control". So if cyclades-ser-cli provides the virtual device named
"/dev/modem" then it will have a control socket named "/dev/modem.control". There is a shared object named libcyclades-ser-cli.so which
intercepts calls to the tcsetattr() and tcsendbreak(). This shared object then sends the relevant data to the cyclades-ser-cli server via
the control socket. To recognise a virtual modem device it has to read /etc/cyclades-devices.
The libcyclades-ser-cli.so shared object can be loaded per-application through the LD_PRELOAD environment variable, or for the entire sys-
tem through the system shared object configuration (see the OS documentation). Note that the LD_PRELOAD environment variable has to have
the fully qualified path of the object, otherwise an application which changes it's current directory may fail.
BUGS
In Solaris libcyclades-ser-cli.so does not work with the stty program. stty uses a different interface to this and requires some extra
coding.
In Solaris libcyclades-ser-cli.so conflicts with some system programs such as ps for unknown reasons. Just don't load it for those pro-
grams, it has no such problems with any serial comms programs.
EXAMPLES
Start an interface between /dev/prt1 device and a serial port number 10 of a Terminal Server named pr01, without hangup at last close:
cyclades-ser-cli -c 1 /dev/prt1 pr01 10
In general use do not start cyclades-ser-cli from the command line, start it through the cyclades-serial-client script or from init.
