To ensure a hangup without using "+++ ATH" you need to lower DTR. BBS software routinely set S2 to 128 to prevent any remote tampering of the escape sequence. Thus many BBS softwares will hang up the modem by temporarily lowering DTR.
I am using V2.70 of the firmware.
I have tried to set &D2 to cause the WiModem232 to hang up when the computer lowers DTR, but it won't sustain a connection.
As soon as a connection is made, the WiModem232 hangs itself up immediately. (The voltage signal from the computer is +12 volts with DTR is high.)
When I set &D0 the modem can sustain a connection, but won't hang up when the computer lowers DTR.
When I set &D1 the modem can sustain a connection, but also won't hang up when the computer lowers DTR.
Also, the WiModem232 does not seem to do anything with DSR.
My BBS software (and many others) look at DSR to see if there has been a remote hangup. I can set &S0, &S1, and &S2 and in all cases the WiModem232 does nothing on connect or disconnect. It just doesn't change state at all.
