This is a WMP100 application. UART1 interface utilizes TX1,RX1,RTS1,CTS1 and it works okay. Don’t seem to be able to use DSR1,DCD1,RI1 as GPIO pins while UART1 is enabled. Is this possible in OpenAT 7.1a? Eddie :question:

UART1 handshake signals as GPIO

Wavecom support says no.
Only way to use any UART1 handshake signal as GPIO is to disable UART1.
Rats!
