this patch to qcserial.c enables the Diagnostics Monitor and NMEA GPS ports on Qualcomm Gobi 2000 devices. A Gobi 2000 device will provide 3 serial ports: # /dev/ttyUSB0 -> Diagnostics # /dev/ttyUSB1 -> 3G Modem # /dev/ttyUSB2 -> NMEA GPS port * The Diagnostics Monitor uses Qualcomm's DM protocol; I used libqcdm (ModemManager) to talk to it, found it working, but at least DM commands 12 and 64 are not implemented on my device (Gobi 2000 built into Thinkpad x100e). * Functionality of the 3G Modem port remains unchanged. * The GPS port and how to enable it has been confirmed now in the Gobi 3000 source code at: https://www.codeaurora.org/patches/quic/gobi/ Enable/disable GPS via: echo "\$GPS_START" > /dev/ttyUSB2 # use GPS echo "\$GPS_STOP" > /dev/ttyUSB2 Signed-off-by:
