PC104 Serial Port Programming

I am working with a SBC1390 and I am attempting to write a program
which will read and write data out of COM1, COM2, COM3, and COM4. I
have COM3 and COM4 working as they should however I cannot get COM1 and
COM2 to work for the life of me. I am writing the program in C and
like I have said the code works just fine on my PC and for COM3 and
COM4. I will say that COM1 and COM2 are independant of COM3 and COM4.
Is there anyone out there who might be able to shed some light on this
issue. Thanks
