I am using a pair of Telebits TB+ to transfer files between California and Europe and getting about 450 bytes/sec for large files. Is that decent? Our uunet connection at 19200 bps averages about 500 bytes/sec for ALL the transfers, with both large and small files. I don't have other statistics to compare it with. If you do, I would like to hear about it. While a large file transfer is going on, I noticed that the SD and RD LEDs on the TB+'s front panel flashes for about 2 seconds, pauses for about 3 seconds, and then flashes for another 2 seconds, and so on. Is this normal? I was expecting to see a long (hopefull non-stop) blast of SD and RD LEDs flashes, but I don't. Is this 3-second pauses normal? In order to make UUCP work across the Atlantic, I have to set S120=12 and J6S36=2 (as suggested by Pete Holtzmann 6 months ago). Does anyone know if these S register settings slows down transmission? -- -- Peter K. Lee (...!uunet!daisy!pkl), Daisy/Cadnetix Inc.
