Hi, I'm trying to install a USB 3G modem, a HUAWEI E220, but when I run # comgt -d /dev/ttyUSB0 I get the error: "[root at deckard files]# comgt -d /dev/ttyUSB0 comgt 19:12:30 -> -- Error Report -- comgt 19:12:30 -> ----> ^ comgt 19:12:30 -> Error @74, line 4, Could not write to COM device. (1)" I've google about it, but find anything useful. Any ideas ? Any help would be appreciated. Warm Regards, Mário Gamito
