[linux-vr-cvsupdate] Update to module linux

[Jay C. <no...@us...>]

Update of /cvsroot/linux-vr/linux/drivers/char
In directory slayer.i.sourceforge.net:/tmp/cvs-serv8786/drivers/char

Modified Files:
	r39xx_serial.c 
Log Message:
Tell generic_serial driver when we've turned off TX interrupts.  Without
this, tx is broken. 

Also,
a udelay(1) in rx is enough to receive many megabytes with 1k XModem, so
it seems safe to reduce from udelay(10).
