Dongle/Module1

•

S15 should be set to 0x00 (using HyperTerminal write ATS15=0x00)

•

S16 should be set to 0x01 (using HyperTerminal write ATS16=0x01)

•

Then send AT/C to store settings and ATO to move into operation mode

Dongle/Module2

•

S15 should be set to 0x01 (using HyperTerminal write ATS15=0x01)

•

S16 should be set to 0x00 (using HyperTerminal write ATS16=0x00)
