Hi, I could not talk to my LG VX1 phone/modem (aka LGE-TM520 72), using both minicom and setserial. The phone has a USB cable which supposedly should look almost like a regular serial port and a modem once connected.
My kernel (Linux 2.4.9-31 and 2.4.18-3) could detect the USB-Serial Converter as FTDI 8U232AM (vend/proc 0x403/0x6001). It attached the converter to /dev/usb/ttyUSB0 (see log below). When running the command "setserial /dev/usb/ttyUSB0", I got the error "Invalid Argument". (Strace shown that it was an ioctl() failed with EINVAL). When running minicom, I got no response from the modem in the phone (I was using the speeds of 57600 and 230400 and various other speeds). However, in some occasions I did see some garbage echoed back (this happened when I switched from 230400 to 57600 baud rate). The following four kernel modules were successfully loaded: ftdi_sio usbserial usb-ohci usbcore In /proc/tty/drivers, a usb-serial driver was listed: usb-serial /dev/usb/tts/%d 188 0-254 serial However, there was no file called /proc/tty/driver/usb-serial. (Some other documents had suggested that there should be such a file.) I have no problem using the same phone/modem on a Windows machine, where this phone appears as a device "Ports->USB Serial Port (COM3)" and "USB Controller->USB High Speed Serial Converter". I also attached a dump from my /proc/bus/usb/devices Any idea? Please cc your response to my email address ([EMAIL PROTECTED]) also as I haven't yet been able to subscribe to the list. Many thanks!
