SYNOPSIS:     Workaround for the 'cu' error message on Solaris 2.1 for x86

OS RELEASE:   2.1

PRODUCT:      Solaris x86

KEYWORDS:     cu error message device access


DESCRIPTION:

Accessing a 'cu' device, e.g.  /dev/cua/a, at second time using 'cu'
command, it generates an error message such as:

                 "CAN'T ACCESS DEVICE" 


SOLUTION:

Apply patch id #101475-01

Workaround -

Use 'tip' command instead, or, before executing 'cu' command, reset the
permission on the device file you are accessing by executing 'chmod 666'
on the device linked to by the device file.  For instance, if you are
using '/dev/cua/a' for the 'cu' device file, do the following:

   # ls -l /dev/cua/a
     you will get something like this:
     /dev/cua/a -> ../../devices/eisa/asy@3f8,0:a,cu
   # chmod 666 /devices/eisa/asy@3f8,0:a,cu
