I have written a communications client application, but I am having trouble with a really basic problem. That is, sometimes, I cannot force a hang up. I have tried "ATZ" (software reset) and "ATH0" and "ATH1" to take the line of and on again. Even after I issue these commands I can pick up the phone and the line will still be active (i.e. szszszszszszszszszsszszsz). Any help would be appreciated --- Robert |(8>

Had the same problem.... The line will go ONHOOK with Mi/Mic on, but it takes several seconds. A/A1 will let the modem put the line onhook as as soon as it hangs up.

The sure fire way to do it with both modems is to drop the DTR signal
for about a second. The default settings on most modems will cause them
to hang up. For this you need to have access to routines which can access
the hardware in such a manner as to be able to drop the DTR signal and
then raise it again. On what kind of system is this installed?? What
developement environment did you use?? (ie: what language and compiler?)
