Update of /cvsroot/src/sys/arch/amiga/dev
In directory nb00:/tmp/cvs-serv21621

Modified Files:
        ser.c 
Log Message:
The INTF_RBF bit of INTREQ is mirrored in SERDAT. As we would read this
register anyway when the bit is set, we can safe one of the (slow) custom
chip accesses by using this bit.
Sounds ridiculous, but at a hardware FIFO depth of 1 and ~1 usec per
access (at IPL 5) it might help the highspeed addicts.
