# Configures a CTC device by calling the IBM-provided chzdev command.
|
||||
# Whereas this script used to validate the parameters provided to it,
|

# we now rely on chzdev to do that instead. The script is intended only
|

# as a "translation layer" to provide backward compatability for older
|
||||
# scripts and tools that invoke it.

# Configures a CTC device
|

#
|

# Usage:
|

# ctc_configure <read channel> <write channel> <online> [<protocol>]
|
||||
#
|
||||
# read/write channel = x.y.ssss where
|

# x is always 0 until IBM creates something that
|
||||
# uses that number
|
||||
# y is the logical channel subsystem (lcss) number.
|
||||
# Most often this is 0, but it could be non-zero
|

# ssss is the four digit subchannel address of the
|

# device, in hexidecimal, with leading zeros.

# online = 0 to take the device offline

# 1 to bring the device online
|

# protocol = 0 Compatibility with peers other than OS/390®, or z/OS, for
