If the device provides a couple serial ports alongside cdc-wmd0, then one of them may be a GPS port as is common with Gobi-based devices. So you may be able to follow these directions: http://www.thinkwiki.org/wiki/Qualcomm_Gobi_2000#GPS and get it to work with the 7354 too. ModemManager gets location info through the QMI interface, not the AT serial port, so it should not conflict with your parallel usage of the GPS tty. If the device doesn't provide the standalone GPS tty, then you'd have to modify your workflow to use ModemManager's location API instead, which does have the ability to output text-based GPS strings, but does so through the D-Bus API rather than a serial port.
