Message-ID: <14627@mgweed.UUCP> Date: Wed, 2-Jan-85 18:58:19 EST Article-I.D.: mgweed.14627 Posted: Wed Jan 2 18:58:19 1985 Date-Received: Fri, 4-Jan-85 04:02:36 EST References: <163@uf-csv.UUCP> Organization: AT&T Consumer Products - Montgomery Illinois Lines: 20 We've had higher than normal failure rates on the S-muxen, too. Of course, with the 20/100's and 20/200's, "normal" meant one or two out of 75 or so, and most of them were un-seated boards from shipment. We have also noticed operational problems with the S-mux. Whenever we'd use one for people ports (human at a 20/100 calling the S-Mux) the charcter echo got real fragmented like there were some contention problems. So we put the S-muxen on the outgoing (wrt computer) ports for the lineprinter system and uucp where the problem is not noticeable. Then we noticed a bit of DTR/DCD problems; at times sessions would close just as they were opening. We have not investigated further; nor have we bought any more S-muxen. I might also add that we have not pursued it with the Sytek people either. Other problems have been taken care of promptly. Randy King AT&T-CP@MG ihnp4!mgweed!rjk
