NAME
     ispcvt - verify if current video driver is pcvt driver



SYNOPSIS
     ispcvt [-c] [-d device] [-v]

DESCRIPTION
     The ispcvt utility allows the user to check whether the current video
     driver compiled into the kernel is a pcvt driver. The major and minor re-
     lease numbers of the driver are also checked.  Furthermore ispcvt is also
     able to print out the values of all the ``PCVT_XXXXXX'' compile time op-
     tions, the driver in the current running kernel was compiled with.

     The options are as follows:

     -d      Specifies a device for which the check is done.

     -v      Specifies being verbose. On success the name and revision is re-
             ported, on failure which comparison failed.

     -c      This options prints out the values of all ``PCVT_XXXXXX'' #de-
             fines which were given to the compiler at the time the currently
             running kernel was compiled. Specifying -v with the -c option
             gives a verbose listing of the compile-time options.

RETURN VALUE
     0       driver is pcvt and major and minor numbers match

     1       open or ioctl system call failed

     2       driver name mismatch

     3       name matched, release major number mismatch

     4       name & major number matched, release minor number mismatch

     5       usage error

BUGS
