I noticed some weird behavior last night. I was dialed into the office from home. I was uploading some files via ftp. The modem send light started off blinking rapidly (basically flickering) indicating high traffic. Then it suddenly backed off, maybe sending about 1 packet/second. It stayed like this for maybe 30-60 seconds & then sped up again, but not to as fast as it was initially. Final throughput was a little on the low side.
Details: I'm running 2.2.0pre9 at home. I was dialed into the office via pppd, connecting to a linux box running a 2.0.3x kernel. I was uploading to another linux box (2.0.29 kernel), which is on the same ethernet as the box hosting the modems.
