If you do, I would like to hear about it. ! ! I have witnessed a good link between TB sites average in excess of 1730 cps. ! You are correct in assuming that the SD/RD lights should remain constant. ! ! They do. I don't know why I am having trouble, but connecting at 9600 baud, ! I average about 850 cps. We're getting a BAD throughput too. About 550 CPS on a TB+ for a trans-atlantic link. This really sucks! A local FIDONET Sysop with an HST claims he gets 1000 cps on average on trans-atlantic calls! I thought the TB was a vastly superior modem. Either I was wrong, or my setup is wrong. We have s120=12 (supposed to be an undocumented feature for trans-atlantic links), but still get only 550 CPS. Any help would be appreciated. I would expect to get OVER 1000 CPS with a trailblazer, or else maybe we should switch to an HST. thanks aris -- Aris Stathakis | Bang: ..!uunet!ddsw1!olsa99!tabbs!aris or aris@tabbs.UUCP - UNIX is like sex - if you've tried it, you can't get along without it. - - If you haven't you really have no idea what the fuss is all about! -
