Message-ID: <2424@sri-arpa.UUCP> Date: Wed, 22-Jun-83 17:18:12 EDT Article-I.D.: sri-arpa.2424 Posted: Wed Jun 22 17:18:12 1983 Date-Received: Fri, 24-Jun-83 13:41:43 EDT Lines: 14 From: Lauren WeinsteinAny modem manufacturer who tries to power equipment from the RS232 lines should be hung upside down by his or her "chips". If powering a modem from the phone line is bad, powering from the RS232 lines is simply AWFUL, and potentially damaging to some equipment. Manufacturers who use these gimmicks are trying to save the cost of a UL-approved tranformer plug. Don't fiddle with modems that do not use A.C. power -- they are simply not very reliable in the long run. --Lauren--
