can you suggest a terminal available on roundsolution.com and compatible with old telit GT863 ??
I need to use DTMF commands.
I try to buy a GT864 terminal (telic.de manufacturer) from ebay, but DTMF tone dosn't function
if i send AT+CGMM -> GE865
if i send AT+cGMR -> 10.00.03
i remenber that also GT863PY needed to be update in order to work with dtmf command.
