the COM port of USB GSM modem is not recognized automatically -


i have d-link usb gsm modem , developing application using c# serialport class , @ commands. everything, such sending , receiving messages, works fine. have problem modem initialization. each time connect modem usb port have run modem's own connection manager program called d-link connection manager. otherwise, neither computer's device manager nor hyperterminal not recognize , com port. believe d-link connection manager creates virtual com port modem. not want application depends on d-link connection manager time. have suggestion can recognize modem's usb com port (virtual port) automatically? appreciate beforehand.

since d-link connection manager cannot used in linux os, issue problematic if try use modem on linux systems.

ps: problem not exist when use older gsm modems serial port connection.

you should able see such virtual com port in device manager. don't know d-link modems, know usb connected barcode scanners (symbol/motorola or datalogic), there special virtual com port drivers create such com port usb connected scanners can accessed through com port.

while may not comfortable, still necessary, because usb connected devices can not accessed through com ports default.
