In-Reply-To: <memo.961264@cix.compulink.co.uk> Well, I found my problem. Ameol, the online reader for CIX, has an option to monitor for carrier detect. It would seem that the Mwave DSP modem does not supply this DCD signal to the application. Turning off the option gets me perfect 28800/ECLC connections every time. Next question, what is ECLC ?
