when we connect them first time they didnot work
but after install their drives
both work fine and we send sms using them
the problem we want to interface them with MCU (pic)
(as i think drivers installation only make VCOM (virtual serial port) so we donot know we will need that or just it is software issue)
could we use any USB to serial adapter and interface serial with MCU ?
(i have tried to interface 6100 as i have serial connection for it but i have got no response with hyberterminal)
