Subject: How-to disable irq4 serial ints
Date: Thu, 9 Jun 2005 19:49:28 -0800	[thread overview]
Message-ID: <20050609194928.308e356b.tonyb@sysdev.org> (raw)

I am forced to use a legacy assembler serial driver that handles a
special comm port device and preps data for a dos text gui.

Problem is, if the serial device on /dev/ttyS0 is receiving
data and generating ints, this serial servicing tsr crashes
during its init.  But if the port is quiet it starts fine.

So, I ask for suggestions on ways to temporarily disable irq 4
interrupts from happening, until after this tsr starts ???

Thanks in advance
TonyB
