We have a number (100+) of dialin users from all over the country who have recently been complaining of increased line noise when dialing in at 1200 baud. We are using DEC's rackmount DF03 modems in our VAX 785, and are researching a number of different ways of circumventing the noise problem, which is affecting about 30% of our remote sessions. One avenue being investigated is the use of cleaner modems. Interestingly enough, both PC Magazine and PC World surveyed 2400 baud modems in their latest issues. PC Magazine's review was limited to the cosmetics of cabinetry and switch access, general overall sex appeal. PC World's however, tested the Ceremtek, US Robotics, Hayes and Novation series with sophisticated equipment which duplicated three different line noise problems. The Novation was the clear front runner in these tests. While we are investigating other solutions, such as the use of Tymnet, Telenet, etc., I would like to know the general experience of the net as to any of the above mentioned modems. The PC World article suggests that modems can vary greatly in their ability to endure the low quality phone lines we are all suffering with these days. Whaddya say, guys? Thanks Brian%src@csnet-relay

InfoWorld recently ran a rave review of the AT&T 2224B modem observing in particular its outstanding resistance to noise problems. They also suggested that it had setup options beyond what were needed for most micro use. These were options to configure it for central site use but they gave no details. List price was given as $949 (add $50 for autodial), information at (800) 247-1212. Thos Sumner (...ucbvax!ucsfcgl!ucsfcca.UCSF!thos)
