 * Ioctl's to control telnet protocol module
 * (See also, logindmux.h LOGDMX_IOC_QEXCHANGE)
 *
 * TEL_IOC_ENABLE: Allow processing, and forward normal data messages.  This
 * resumes processing after telmod receives a protocol sequence which it does
 * not process itself.  If data is attached to this ioctl, telmod inserts it
 * at the head of the read queue.
 *
 * TEL_IOC_MODE: Establish the mode for data processing.  Currently binary
 * input and output are the only modes supported.
 *
 * TEL_IOC_GETBLK: When telmod is not enabled, this ioctl requests that
 * the next input message from the network to be processed is forwarded
 * through the mux to the daemon.
