mode a b c

Sets the required functionality of the serial ports.

a	The function of ttyAM0 (Primary DB9) (port 1)
b	The function of ttyAM1 (Secondary DB9) (port 2)
c	The function of ttyAM3 (RS485) (port 3)

Mode	Serial Port Function
1	None
2	Console
3	PPP
4	PAD host interface
6	MODBUS host interface
9	Magnetic Card Reader interface
10	WPAN Gateway
12	Chlorobyte Spreader Controller interface
13	external GPS receiver
15	Epomaster Spreader Controller interface
17	Garmin mode - client/server
18	Garmin mode - client only
19	Garmin mode - server only
20	WPAN PAD client loopback
22	Auxiliary device support
23	Auxiliary device support (polling device, e.g. Bosch Spreader, Dickey John Salt Spreader)
24	Auxiliary device support (non-polling device, e.g. Parker Spreader)

Notes:

default is cmd mode 2 0 0
ttyAM2 is used for STM communication.
To escape out of the mode (to get a command prompt / console) do the following:
- mode = 3 : type EXIT, type cmd port n bbbb (where n is the serial port number and bbbb is the current baud rate)
- mode = 4 : type +++, wait 3 seconds, type cmd port n bbbb (where n is the port number and bbbb is the current baud rate); Refer to pad esc and pad esct for escape sequence

Examples:

Set primary serial port to use Console, and secondary serial port to use PPP :
cmd mode 2 3 0

Set primary serial port to use Console, and secondary serial port to use client mode connection for external Garmin communications :
cmd mode 2 18 0
