mackrackit's ConnectOne example code

[jellis00]

I have only used the Nano LANReach, Nano SocketLAN, and Nano Socket iWiFi modules. The only data connections used are the TX and RX from MCU to the ConnectOne module.

Dave,
I have been reviewing the data sheet for the MiniSocket WiFi module and can't find ansers to following questions. Can you or anyone else on this thread answer them??
1)When using a UART serial interface from the MCU to the MiniSocket to perform asynchronous data transfer, should the TXD pin of the MiniSocket be connected to the RX pin of the MCU? Similarly, should the RXD pin of the MiniSocket be connected to the TX pin of the MCU? I ask this because the Nano WiReach reference design sent to me by ConnectOne has TXD to TX and RXD to Rx, which is contrary with most MCU serial interfaces I have seen.
2)We are not going to use flow control on the serial interface so we are tying the -CTS and –RTS pins together. However, we can’t determine from the MiniSocket data sheet whether we need to use the handshaking interfaces with DTR and DSR or not when performing asynchronous serial data transfer with the MiniSocket from the MCU. I notice the ConnectOne reference design for the Nano WiReach did show the DTR and DSR interfaces implemented, yet in most asynchronous serial interfaces we have seen with a PIC MCU they are not used. Please clarify??
3) It is my understanding that the MiniSocket (which is a 3.3 v device) is not tolerant to 5v logic signals. Our application is all 5v circuits. Any suggestions on how to convert the 5v logic of the MCU to 3.3v logic for the MiniSocket with minimum hardware....our board is already very densely populated and can't afford a lot of additional components.

Really appreciate any comments/answers to these questions.
