Huh? To: questions@freebsd.org Date: Wed, 3 Jan 1996 20:52:00 -0800 (PST) X-Mailer: ELM [version 2.4 PL24 ME8b] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-questions@freebsd.org Precedence: bulk Okay, first my setup: - FreeBSD 2.1 running IIJPPP w/tun0 running at 750 MRU - Supra 28.8bps external FaxModem w/latest ROMS, hi-speed UART, etc - Connected to Port Livingston terminal servers w/US Robotics Courier v.Everything's When the receive speed of my modem is set to 24.4 - 26.6bps, everything is smooth as silk. When I get a true 28.8 connection, however, my throughput slows down to about 1/10th the speed it was running at w/26.6bps or below. At 28.8, I'll get a burst of something, then nothing for a couple seconds, then another burst, etc. At 26.6 data just streams away. Any ideas from the software side what this might be before suspecting hardware?
