[CLUE-Tech] Wireless Barcoding thru Linux Port

That's it, I'm leaving.  Bad enough we have too many Daves around here, 
now we got two Dave Ws. ;-)

That means the OS isn't doing anything with the serial device.  In other 
words, not running getty (or its cousins) on it.  Just make sure there 
is no getty line in /etc/inittab for /dev/ttyS3.

As to buffering, I don't know about that (but perhaps the default is 
good enough).  You can look at the setserial man page -- that's the only 
one I know of for serial port devices.  There might be more in the 
kernel docs.

As I said, you don't want any getty at all.  What program is going to 
talk to this device?
