Javax.comm doesn't enumerate more than 2 serial ports (linux)

I am using javax.comm v3.0u1 on a PC104 single board computer and ports /ttyS0 and ttyS1 work great and are enumerated.However I have an addon board attached that provides 4 additional ports. These additional ports javax.comm cannot enumerate and cannot communicate to.

I used setserial to setup my additional ones and setserial -g to check them. I can use curecom terminal to communicate on ttyS2-S5 but the java example only enumerates the first 2.

For example, at the linux terminal I performed the following command to configure my addtioanl port ttyS2:

setserial /dev/ttyS2 port 0x0100 irq 7 autoconfig

setserial -g /dev/ttyS2

Is there more I have to do in order to get javax.comm to see the additional ports?
