tar.gz or other compression

Data compression (for transmission from an SB70LC to a remote host) is useful and desirable for my application.
The RTL's do not offer any compression utility (that I can find).
Anyone out there (here) who has dealt with this? Did you end up creating your own compression tool?

we use a simple compression implementation of lzo. it is a gnu, gpl, package. their site is:
/*
* NOTE:
* the full LZO package can be found at
*
http://wildsau.idv.uni-linz.ac.at/mfx/lzo.html
*/
it had a few anti-aliasing type compile warnings under nb, but all has worked flawlessly.

greengene,
Thanks for that info on the compression. The link you gave did not work but I was able to find the main page here:
http://www.oberhumer.com/opensource/lzo/
I also successfully tested the miniLZO on a MCF5270 platform:
http://www.oberhumer.com/opensource/lzo ... .03.tar.gz
Be aware that this compression software distributed under the terms of the GPL v2+.

thanks for correcting the link.
i just did a cut-n-paste from the code and who would
ever expect that a comment was no longer current
