No. 104	using Flow Control = NONE on EZL-80	2006-04-19

I have connecting a HC12 processor up to the EZL-80 using the GND is common and then RX and TX on EZL-80 are connected to TX and RX on HC12 I down convert from 5v to 3.3V TTL like yousay in the manual, my problem is that once I have this connected I still get no communication between the EZL-80 and HC12. But if I disconnect teh RX and TX lines and use a RS232 device and connect the HC12 to the EZL-80 through the RS232 device with Flow control = CTS/RTS then I get great communication??? what did I do wrong in the flow control = none connection?????
