I don't know why it is not locking. Are you using /dev/modem,
correctly linked to /dev/cua0 or /dev/cua1 or something like that on
/dev/ttyS0 or /dev/ttyS1? And is there another process living on
/dev/cua2 or something like that, using the same IRQ?

Celeste Stokely's web page at www.stokely.com. It also explains the
