The datasheet says this on page 14:

Receiver Echo Mode (Bit 4)
A 1 enables the Receiver Echo Mode and a 0 enables the Receiver Echo Mode.

Is it a typo or is it really impossible to disable echo mode on this chip ?

I think it should say,

    A 1 enables the Receiver Echo Mode and a 0 disables the Receiver Echo Mode. [...]

I've never turned on or used echo mode.

In such cases it helps looking at the datasheets of the 'sister' chips like the R6551 etc.

Thanks for the replies. I think my code does not enable echo mode but I still get an output of whatever I send. I will double check everything and try to find where the problem is.
