Do you think the DSerial Edge can support 5V TTL comms?

According to microcontroller's datasheet, it can handle 5 volt signals as digital inputs, but it will only provide 3 volts (microcontrollers supply in fact) as digital output.

You can check the Application Note 111 (C8051FXXX IN 5 VOLT SYSTEMS) to get some tips regarding your question.

... thank God for 74C & 74HC ICs :D
