Increase agi buffer?

I’m trying to pass an XML string from dialplan to an agi script to parse then send a selection back. The CLI output show’s me it is being cut off, and when I run a dif data set it works the way I want it to. Can I increase the character or buffer limit in asterisk to allow me to do this, and if so, how do I do it. Thank you so much in advance, any help is much appreciated.
