(Oops -- I replied to this a couple of days ago, but it seems I send a private reply instead of following up to the mailing list... Here's my reply again.) Unless the modem on the other side has a slow serial connection to the server computer (which is the case for my connection). Even with 33600 bps modems you would need a 115200 bps connection to the computer, and with a 57600 bps modem you'd need an even faster connection. I'm currently tunneling the NNTP connection via SSH. This gives me a compression of about 3:1 and much better performance than when I only used the built-in compression in the modem. (I use "suck", not the agent features. Normally I run a couple of parallel "suck" programs in order to use the available bandwidth better.)
