<p>A ttyrec produced on one kind of terminal will not play properly on a different kind of terminal. Most modern terminals are similar and should produce
compatible ttyrecs, but you might come across a file that won't work.</p>
<p>Replaying also might not work properly if your terminal is a different size from the one that produced the ttyrec. If things are getting drawn in the
wrong places, try making your terminal bigger. Unfortunately, ttyrecs don't tell you what the proper size is.</p>
<p>(But it can sometimes be deduced, if you don't mind poking around with a hex editor. Check near the beginning for the sequence
<span class="metavar">&lt;escape&gt;</span>[1;<span class="metavar">&lt;number of rows&gt;</span>r )</p>
wrong places, try making your terminal bigger.</p>
<p>Unfortunately, ttyrecs don't contain any metadata which could tell you what the proper size is. But most recent files from the Gallery and similar sites
work around this limitation by putting some invisible text at the beginning. You can read it by opening the ttyrec with a hex editor or text editor. There
will be a line starting with "Size:" followed by the terminal width and height.</p>
<p>Note: if you are using ipbt, you must also tell ipbt what size terminal to use. Check ipbt's documentation.</p>
