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!

I need to access the serial port via python on a windows machine.
Reading on the web, there are three solutions: pyserial, siomodule and
USPP. pyserial seems to be the best option since the other two are
tested with Windows 95 and older versions of python. Would you agree
with this or have I missed an option?
Can anyone provide me an example of how to access the serial port with
pyserial?
Thanks

Hello at all
sorry for my english but i'm Italian.
I use pyserial to communicate via rs232 with an extarnal device called
smartmouse.
I write the exact line that i want , but when i read i read only the

call of the sleep.
But in python it don't work.
Have you got some ideas for solve my problem?

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...

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
