@HakamSaffour this PR looks like a bunch of stuff got thrown into the 1-line change you were trying to submit. Please look at it and clear out the unneeded changes.

@HakamSaffour It seems you didn't start your pull request on top of the master branch.
You have the option to fix it, or you can start over from a fresh git version of the master branch.

Hello @earlephilhower and @d-a-v
I do not have access to create a new branch, therefore I went to branch 2.7.4 and added my changes to uart.cpp

One more thing: I do not have access to change uart.cpp on the master branch.

Can you explain to me, how to create a new branch? or can you do it yourself?

I am closing this PR

You need to

git checkout master
git pull upstream master      # upstream is esp8266/arduino
git checkout -b mypatchname   # create your local branch
# apply your patch
git add -p                    # add your change to the branch
git commit
git push origin mypatchname     # push your changes to your repository/clone on github

Then on gihub you have the ability to create the PR.
