Nope. In the Microchip Databook (1994) 16C74 chapter, section 12.2.2
deals with asynchronous transmission, and in the paragraph starting with
"Steps to follow ...", the third step says:
"Make sure CREN=SREN=0 (these bits override transmission when set to
1)"

and as I read it, transmission OR reception is selected by these two bits.

IN SYNCHRONOUS MODE.
