Is there any way check or know the serial port information & do SERIAL OUTPUT TEST of my computer to make sure theres no problem without buying a software to test it like GRAHAM utilities OS/2 version...

How long is the cable? Do you have any serial-port specific settings in your software or does it use a fixed setup? You could try some slower speed.
To rule out any issues with the computer, try another (older?) machine. Nowadays, the serial port is an annoying legacy device and I'm pretty sure system designers don't pay much attention to it.
In Device Manager, make sure that the serial port is not sharing interrupts with other devices.
It could also be that the hematology unit is bad. Some other serial port device (another computer over a null modem cable) would be a good thing to test with..
