SERIN/SEROUT via built in RS232 connector

Hello,
I have BS2sx, the OEM module.
I need it to communicate with another RS232 device, using the already built in 9pin port on the board.
The only pins i need are receive/transmit
So is what is the BS2 pin number for RS232 port pin2 and pin3?
Willl SEROUT 16,BaudRT, etc.... send info to pin 2 or 3 on the RS232 port?

Thank you,

Boris.

    Yes, doing a SEROUT on (virtual) pin 16 actually transmits the data out the DB-9 TX pin (2), and SERIN on (virtual) pin 16 receives data from DB-9 RX pin (3).· The attached diagram shows how the programming port is connected on the BASIC Stamp.
