Well, 110 bps is a bit on the slow side--great for teletypes, not so
much for video terminals.   But you'll have to change the hardwired
jumpers--the UART used in the CT1024 is not software-programmable.

If this were my unit, I"d probably solder some pins into the pad holes
and then either use slide on jumpers or wirewrap to set the
characteristics.  That way, when changing things around, you won't be
stressing the PCB.

Something like this:
