Units: N/A
Default: 0
Range: 0, 2, 3, where 0=RS232, 2=RS485 full duplex, 3=RS485 half duplex
Following example shows how to setup and save ASY 0 in 485 half-duplex mode

AT\port
The at\port=0 is needed to ensure that subsequent AT commands are directed to the right port
(ASY0). The port settings can be saved permanently using AT&W.
Issue the command ats16? and check that the value of this S register is 3. To set it back to RS232
then set ATS16 to 0 and save it with the &w command.
