Help with comunication RS232 to RS-244-A

HI
I have an old CNC lathe with a Yasnac 2000G controller. The lathe works
well and I can write programs manually with the key pad. I would like to send
and receive programs into its memory through its Tape reader port (DB25). It
has a 4k character electronic memory but the communication port is for a tape
reader and uses all 25 pins of a 25pin connector is there a translator I can
use to send RS232 to a EIA RS-244-A or ISO R840 ?. I would assume that RS-232
is serial and RS-244 is parallel bit transfer is this correct? What are these
standards and are there programs that I can configure to send info like the
tape reader would? What are my options? I have a tape reader/puncher also but
of course would like to eliminate its use. Any info Links ect greatly
appreciated.
