Drop caller problems

[b_williams]

I have Conexant D850 internal modem that does not drop callers. There is an entry in the log but the caller is not dropped. I assume the default Drop Caller AT commands do not work with my modem. Does anyone know of any alternate AT commands that might work ???

Thanks,

drop caller

I use the following to drop calls on a HIRO H50113 USB modem:

AT+FCLASS=8
AT+VLS=5
atdt,
ATH

All lines except the one in small letters (atdt,) are default. I just asked the modem to dial using touch tone but the only character I gave it to dial is a pause. You could give it actual numeric digits instead...doesn't really matter since the command will fail when there's no dialtone. With the default init the modem would not go off-hook, so the ATH (hang-up) didn't work to drop the call.

It produces an error in the HS log, but the modem goes off hook momentarily when it tries to dial. The error could probably be eliminated by playing with response code settings so the modem doesn't return an error when the atdt, doesn't get dialtone but I haven't bothered yet.

I also tried putting in ath1 (force off-hook) and ata (force answer) before the ATH but that didn't work. Either should have taken the modem off-hook but didn't. Somehow the atdt, does take it off-hook so that the ATH on the next line can hang up.

Anyway, good luck.

Thanks for the suggestion. I got tired of fighting the Conexant modem and purchased a Hiro H50113 external USB modem. It works perfectly.
