Would you happen to know if Redhat 7.1 supports serial com port 5?

Upon linux boot up Linux at first only sees 4 ports ttyS0 , S1, S2 ,S3 then when bootup completes I setserial S4 to proper irq. BUT i cant use it, serial port wont work.

TO TEST SERIAL HARDWARE:
I switched S3 and S4 settings to test and S4 (witch now has
S3 settings) works but S3 (witch has S4 settings) wont...

I have tried 2 free IRQs and same issue..

Ideas?

fixed it!!! redhat saw com5 (ttyS4) as a fourport instead of uart16550 mode... I just added ^foutport at end of setserial. The ^disables function...
