File Tranfer support in Tuxedo Messaging

Hi,
I would like to know if the file transfer support is there through tuxedo
service call or not?

We have a scenario where by we need to bring back .pdf files in the output of a
tuxedo service call which are already created through a process.

I would like to know the following detials about it:
1. The data type supporting the files.
2. Any limitation on the file size.
3. Any special configuration setting requirements.
Thanks,
