[BRLTTY] combi braille (window braille?) in BRLTTY 5.0

[Henk Abma]

Hello,

my sister has been running ubuntu LTS 2010.04 for the last few years. 
Today I updated her to 2014.4, which contains brltty 5.0, which is an 
update from her previous 4.1.

She uses a Tieman combi braille (braille window)? connected through a 
serial port.

The problem is that brltty stops running when it displays information, 
such as a scrolling directory. After a brltty restart, the program runs 
for a while and then stops again.

The 4.x versions have been running stable for years, so is there 
something wrong with this version of brltty?

I am not sure how to update her to 5.2, because I am dependant on brltty 
myself, so if I uninstall the standard ubuntu brltty package, I am just 
as lost as she is...

Getting ssh access to her computer is currently not an option, because 
she doesn't know the password to the configuration screen of her router.

thanks for any information you can provide.

With kind regards,

Henk.
