Right off the bat I am wondering : why you are using /dev/ttyS1 instead of /dev/cua1 (which is one of the : standard call out devices). As I remember, the /dev/ttySx's are : normally used as call-in devices (whether or not this actually makes a : difference to the system I do not know).
No. /dev/cua? devices are deprecated, and should not be used. /dev/ttyS? devices are preferred as this allows locking to occur. This was stated some time ago on the linux-kernel list I believe ...
