Linux Serial Port Commands For Windows 10
Introduction General. This content is part of the Serial Programming book. It covers the programming of Hayes and Hayes-compatible telephone modems. Such types of modems are the norm in consumer applications, as well as many professional applications - basically, wherever modems are still used. Command Line (Windows, Mac, Linux) As mentioned earlier, you can use command line interfaces to create serial connections. The major limiting factor is the lack of connection options. Most of the programs we've discussed so far have a slew of options that you can tweak for your specific connection, whereas the command line method is more of a quick and dirty way of connecting to your device in.
I am looking to send a 'reboot' command over the serial port to the PDU. What I have to do in the interactive mode is this:

If I want to automate this task in a script, I should be able to reboot the PDU with a single command from shell like this:
However, it does not work ! I don't know why.. Would you be able to help me ?
The PDU manual request baud rate of 9600 which is not a default baud rate. I have tried following command to set the baud rate but still no lock:
These outputs does not change with or without screen:

Here is how we fixed this issue:
- Config serial port with RAW setting:
- Send Command using echo with r:
I believe that the above might include a typo. If the above doesn't work, try:

From windows I can communicate with a serial port device using following commands:
Device starts the requested operation.
![Linux Serial Port Commands Linux Serial Port Commands](https://www.linuxprobe.com/wp-content/uploads/2016/11/215422rn4111nn244qgqhe.png)
When I try to accomplish the same operation from a stand alone debian box or from a debian virtualbox instance of the same windows machine, I had no luck so far.
Here's equivalent linux commands(at least I think so)
Nothing happens.
Can somebody please direct me to the right direction?

Linux Echo To Serial Port
3 Answers
will not be interpreted, and will literally write the string
x12x02
(and append a newline) to the specified serial port. Instead usewhich you can construct on the command line by typing CtrlVCtrlR and CtrlVCtrlB. Or it is easier to use an editor to type into a script file.
The
wallykwallykstty
command should work, unless another program is interfering. A common culprit is gpsd
which looks for GPS devices being plugged in.50k1010 gold badges6868 silver badges125125 bronze badges
If you want to use hex codes, you should add
-e
option to enable interpretation of backslash escapes by echo (but the result is the same as with echo
CtrlRCtrlB). And as wallyk said, you probably want to add -n
to prevent the output of a newline:Also make sure that
praetorian droidpraetorian droid/dev/ttyS0
is the port you want.2,81311 gold badge1313 silver badges1717 bronze badges
SCREEN:
NOTE: screen is actually not able to send hex, as far as I know. To do that, use
echo
or printf
I was using the suggestions in this post to write to a serial port, then using the info from another post to read from the port, with mixed results. I found that using screen is an 'easier' solution, since it opens a terminal session directly with that port. (I put easier in quotes, because screen has a really weird interface, IMO, and takes some further reading to figure it out.)
You can issue this command to open a screen session, then anything you type will be sent to the port, plus the return values will be printed below it:
(Change the above to fit your needs for speed, parity, stop bits, etc.) I realize screen isn't the 'linux command line' as the post specifically asks for, but I think it's in the same spirit. Plus, you don't have to type echo and quotes every time.
ECHO:
Follow praetorian droid's answer. HOWEVER, this didn't work for me until I also used the cat command (
cat < /dev/ttyS0
) while I was sending the echo command.PRINTF:
I found that one can also use printf's '%x' command:
Again, for printf, start
cat < /dev/ttyS0
before sending the command.Community♦
