I'd like to read ASCII data from a serial port, but (once again) I'm having
trouble getting started. (Can't seem to find the basic level of docs to
get going <sigh>)
I'd like to use only standard "built-in" modules if possible.
Could somebody offer a simple code-snippet to get me started reading from a
serial port?
Thanks!

Hi there,
I am trying to use pyserial to read data from a temperature logger
device (T-logger). T-logger is based on the DS1615 temperature recorder
chip (Dallas Semiconductor). According to the DS1615 docs, writing to
the chip is performed one byte at a time. To read from the chip, one
must issue the "read page" command (33h), followed by the two-byte
address of the requested page (pages are 32 bytes long). After
receiving this, the...

Hello,
I added a serial-USB converter to my laptop, it appear as USB serial
port COM4, and I wrote an application to read 78k data from this port.
In my VC++ express code, I defined ReadBufferSize = 78k, and
ReceivedBytesThreashold = 78k so that I can get the whole data with
one ReadExisting() method when DataReceived event fires.

I'm writing a driver in Python for an old fashioned piece of serial
equipment. Currently I'm using the USPP serial module. From what I can
see all the serial modules seem to set the timeout when you open a
serial port. This is not what I want to do. I need to change the
timeout each time I do a "read" on the serial port, depending on
which part of the protocol I've got to. Sometimes a return character
is expected within half a second,...

Hi,
I am newbie in python. I am working on Telit GM862 GPS/GPRS module
which has python interpreter built in. But it seems this problem is
pretty much related to general python structure.
I need a promt/terminal when the device is connected to PC. If user
enters a command by serial port and press "Enter" then the data is
read by the device and work on the command. This is similar to
readline() function. Unfortunately there is no...

Hi,
I am using the pyserial module and am trying to read the serial port from an accelerometer (LIS302DL).
It has an option in which you write "*debug\r\n" and then you read the data (three axes output) from the output.
I use hyperterminal with the below settings and it works fine:
baudrate=115200
databits=8

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
