Try doing a "stty -f >/dev/tty00 -ixon -ixoff crtscts" before entering kermit (assuming >you're using tty00). Will that stty setting work? I thought those parameters are reset upon close of the tty device. I myself have experienced this hanging problem that is being described. Personally, I found the com driver too buggy and slow; I recently switched over to using sio under NetBSD (someone on the mailing list had done a partial port), and it has been working a lot better. I'm going to give the com drivers another try when I get my 16550 serial card, however. --Ken
