It should be. It doesn't work very well. It works fine at < 1200 baud, but who buys a 2400 baud modem to run at 1200. At 2400 baud this < modem is intolerant of line noise. I would recommend that people AVOID THIS < MODEM. Mine has no trouble with line noise at 1200 or 2400 bps. On the very same phone lines, the modem it replaced ( an Anchor Automation Volksmodem 12 ) gets annoying noise at 1200 bps. The only problem I have with the PM2400SA is that it sometimes takes two or three tries for it and the modems here at ISC to agree to talk at 2400 instead of 1200. I have no idea whose fault this is. The PM2400SA has no trouble connecting to other modems at 2400, and no one else at ISC has trouble connecting with connecting at 2400. My guess is the two modems are both near the limits on some parameter, and are in opposite directions, so they don't like to talk. -- Tim Smith tim@ism780c.isc.com "I don't practice what I preach because I'm not the kind of person I'm preaching to" -- J.R.
