Its possible since the Serial I/O port on the back of the PlayStation is RS-232 compatible but you'll need to build an adapter circuit to convert the voltages and you'll need to replace the proprietary Serial I/O connector on your PSX with a DB-9 connector.
Here's the build instructions for making such an adapter:

If you don't wanna build the adapter yourself, you can try finding a NET Yaroze serial link cable which pretty much does the same thing but such cables are very rare and expensive.
The things you can do with such an adapter/cable is pretty limited due to the speed limitations of the serial port. The main uses of such a cable is to upload and run your PSX exectuables on a real system (if you don't have an xPlorer cartridge) and to send debug messages to your PC.
Here's the tool to execute PS-EXE files received from the serial port:

bizarro2011: vc precisa de um conversor TTL, esse que vc tem (apenas RS232 para USB) não serve!

Your USB-RS232 adapter requires voltage shifter and you will need to loopback all lines except TX and RX.
You also need DB-9 connector, SCPH-1040 cable and a soldering iron to connect everything.
I suggest you go with Type 79's advice.
It's the cheapest option and it works with the send application so you can upload your homebrew.

On a side note, if anyone is having problems compiling Sony's
SIO Echo Back example, it is because you need to edit
PSYQ.INI under
psyq/bin and add the SIO library
You will need to do this if you use
#include <libsio.h> which contains
AddSIO(9600);.
Otherwise, if you don't want to edit the standard libs (all of which are not actually necessary) then you can link it in your MAKEFILE.
