Hi, I’m a newbie with these modems.
I’m actually working on an old WMOD2 GSM modem.
I usually type “at” then I press Enter (WMOD2 usually sends me the echo on typed characters), so I see on Hyperterminal window:
(I work with no echo on characters typed locally)
On a second WMOD2 modem I type “at”: I don’t see the “at” echo, but I receive the OK answer.
On a third WMOD2 I have the opposite: I see the “at” echo, but I don’t see the “OK” answer on Hyperterminal.
I suppose it could be an AT command to set this behaviour.
Is it real or something wrong with modems?
