[BRLTTY] Revisiting outputting braille from my python script

[Pranav Lal]

Hi Samuel,

When I run the below script, I am expecting to see the word "hello"
displayed on the  display. That does not happen.

The output that I get on my console is:
brl_test.py

[pranav at archlinux ~]$ python brl_test.py

Server version 8

Display size [40, 1]

[

The display however is clear.

I am running the script over a ssh connection.
import brlapi

import errno

import Xlib.keysymdef.miscellany
import time
try:
	b = brlapi.Connection()
	b.enterTtyModeWithPath("")
	print("Server version " +
str(b.getParameter(brlapi.PARAM_SERVER_VERSION, 0, brlapi.PARAMF_GLOBAL)))

	print("Display size " +
str(b.getParameter(brlapi.PARAM_DISPLAY_SIZE, 0, brlapi.PARAMF_GLOBAL)))

	b.writeText("hello")
	time.sleep(20)
	b.leaveTtyMode()
	b.closeConnection()
except Exception as e:
	print("error")
	print(e)

To override any kind of focus tracking you can take the whole control of the
display with b.enterTtyModeWithPath() instead of b.enterTtyMode().
