- Select this option if you want to use channel-to-channel networking
- on IBM S/390 or zSeries. This device driver supports real CTC
- coupling using ESCON. It also supports virtual CTCs when running
- under VM. It will use the channel device configuration if this is
- available. This option is also available as a module which will be
- called ctc.ko. If you do not know what it is, it's safe to say "Y".

+ This device driver supports real CTC coupling using ESCON.
+ It also supports virtual CTCs when running under VM.
+ This driver also supports channel-to-channel MPC SNA devices.
+ MPC is an SNA protocol device used by Communication Server for Linux.
+ To compile as a module, choose M. The module name is ctcm.ko.
+ To compile into the kernel, choose Y.
+ If you do not need any channel-to-channel connection, choose N.
