Let's start with some questions first..
Is this connection serial to serial, USB to serial? Are you sure you are plugged into serial A in the Sun box? How are you connecting: tip, screen, minicom? Why are you using fiber for this? and last, what exactly is the purpose of this connection?
SS thanks for the reply. Little after 7am now going into work in a few and will reset settings
To answer your questions:
1 serial to serial
2 yes only 1 serial port. when I cat or have the program that is reading from the serial port display the data, it is garbled in both instances
3 we have some unique networking requirements
4 the program is designed to read from the serial port
can give you more required detail when I get into work typing this now on phone keyboard and a bit of a pain

System Shock. Problem solved. Went down to Best buy and picked up a couple USB to serial cables and it works.
I had intended on doing the test on another platform thinking that maybe the fact it was going fro 32bit Linux to 64bit solaris was dorking things up. I installed the usb to serial on a 64 bit Centos box
only (leaving the sun box as is utilizing the onboard serial port) and it worked. I then installed the serial cable back on the original 32 Centos box and it worked as well, so the secret was going out serially over the USB port.
I'm ecstatic it finally works. But maybe someone can explain why Linux to Linux it worked serial port to serial port just fine.
