gpsparam input priority port br db p sb fc

This command configures the parameters and priority of the port the modem will use for obtaining GPS information.

input	GPS input to configure (1-5)
input = 1	Use internal GPS module (TSIP) (Not available for CTM200)
input = 2	Use internal GPS module (NMEA) (Not available for CTM200)
input = 3	Use external GPS module (NMEA)
input = 4	Use A-GPS module (NMEA)
input = 5	Use internal GPS module (CTM200 only)
priority = 0 to 3	Data Priority. 0=highest
port	Serial port to use. e.g. ttyS1 or ttyUSB14
br	baud rate (see cmd port)
db	data bits (see cmd port)
p	parity (see cmd port)
sb	stop bits (see cmd port)
fc	flow control (see cmd port)

Notes:

If all enabled ports are available and have valid GPS, the highest priority input is used.
This can feature can also be used for A-GPS since it is outputting NMEA data on a ttyUSB port.
When GPS inputs are configured at the same priority, GPS data will be obtained from whichever GPS input has valid data first, in ascending order from GPS input 0 to GPS input 3.

Examples:

configure the modem USB port for accepting GPS data :
cmd gpsparam 3 2 /dev/ttyUSB0 4800 8 n 1 0

configure the modem external serial port for accepting GPS data :
cmd gpsparam 3 2 /dev/ttyS0 4800 8 n 1 0

configure a CTM200 modem to use internal GPS :
cmd gpsparam 5 0 none
