[BRLTTY] Unable to see displayed text

[Pranav Lal]

Hi Samuel,

Thanks. The example is not very clear. All I want to do is to writhe to a
display. 
When I run my code, I get the following error.
Can't determine tty number

How do I fix this?

As shown in the pydoc3 brlapi example, you need to call b.enterTtyMode()
first.
