How can I programmatically access the description text of the documentation pane of a signal line in Simulink 7.9 (R2012a)?

I have added a description in the property dialog documentation pane of a Simulink signal (right click on the signal -> Signal Properties -> Documentation: Description).

I am looking for a way to programmatically access the content of the description field.

You can use the 'Description' property of the 'porthandles' as shown in the following example:

p1 = get_param('signalDoc/Const','porthandles')

get(p1.Outport,'Description')

% set a new description

set(p1.Outport,'Description','My new Description.')
