Rap not adding text comments as expected

[Maijin]

From @bannsec

I'm attempting to use rap protocol to add comments to a remote r2 server. The setup is:

• r2 ./binary
• =&:12345

Then in a second window (in python):

r2 = r2pipe.open("rap://127.0.0.1:12345")
r2.cmd('T test')

Oddly enough, when I do a r2.cmd('T') in the python window, it shows the text. But when i just do T in the r2 window, it does not show the text.

I'd like to be able to send text/other remote commands to the r2 server that update that r2 instance.
