Try setserial -g /dev/ttyS? /dev/ttyS1? and see if it shows up there. You can get pin status with statserial /dev/ttyS9 Connect a null modem cable from one port to the next open two terminals in first term. do cu -l /dev/ttyS8 -s 9600 in second term. do cu -l /dev/ttyS9 -s 9600 or similar, and see if you can talk with yourself.
