How to send putty commands via a batch file?

Question

So what I'm trying to do is use putty.exe from the command line to open a connection to a serial port. I have that part covered, I get in and what I then need to do is send some commands over the port.

I've tried a -m and a .txt file with what I'm trying to do, but it doesn't seem to work.

commands

<cr>
<cr>
M<cr>
4055222<cr>
test<cr>
N<cr>

I have this so far that opens the session

start "" C:\"Program Files"\PuTTY\putty.exe -load "test"

Any advice would be appreciated!

Did you put the script file on your remote system? Did you make sure the script file only uses Line Feeds and not Carriage Return Line Feed? — Squashman, Sep 05 '17 at 21:02

With Putty the only thing I've found is to use auto-hotkey and write a script to send the commands, with pauses.

I found this after a little more searching: putty from a batch file and a script?

p.s. Have you taken a look at GitBash? I prefer it over putty when I need to do something other than ssh...

How is Git Bash related to this question? – andy Sep 05 '17 at 20:35

"Any advice would be appreciated!" - I would place it under this. GitBash supports Serial as of some months ago. – Dakota Williams Sep 05 '17 at 20:45
I should have mentioned I'm limited to a Windows environment for this. – Kerry Collier Sep 06 '17 at 12:09
If you don't have much CLI experience I wouldn't recommend Gitbash. But you can create a script with auto-hotkey that sends keystrokes so when you're connected you can hit CTRL-E or something and it will send all of your commands. – Dakota Williams Sep 07 '17 at 15:14
If you still want to use -m, check out the link in my answer. – Dakota Williams Sep 07 '17 at 15:17
