mackrackit's ConnectOne example code

I will add..
When ConnectOne says TXD to TX they are meaning cross over.

If I were you I would make a point to start designing things for 3.3... But in the mean time
here are more possible solutions, or the same ?

I should have mentioned that the Mini Socket iWiFi datasheet says for RXD...

Input - Host Data Receive – Asynchronous serial data received from host.

anf for TXD...

Output - Host Data Send – Asynchronous serial data sent to host.

Thanks, Dave. I also got a Tech Support input from OneConnect saying to connect TXD to MCU's RX and RXD to MCU's Tx, -DTR to ground, -DSR unconnected, and -CTS connected to -RTS. So this clarifies the serial interface requirements for their MiniSocket WiFi module with a PIC MCU.

Thanks for the URL to the Tips file. The only reason I am still using 5.0 volts for the MCU is I am using one of the GPIO pins to power on and off a SRF02 Ultrasonic Ranger, which only operates on 5.0v. I am using two LDO regulators, one for 9v to 5.0 v to power the MCU (and the SRF02), and one further downstream for 5.0v to 3.3v to power the ConnectOne WiFi module.
