Read thru the file, they specifically mention the 501 card. The parameters have something to do with the packet size that's transmitted. I don't have the info in front of me so I can't give you the exact details. I remember that our sizes were something like 2k or 4k. We changed them to 512. Our transfer rates jumped from about .2-20kBytes/sec to consistantly above 20kbytes/sec. >PS. Can someone tell me the situation with NCSA telnet ?
