38  * TEL_IOC_ENABLE: Allow processing, and forward normal data messages.  This
39  * resumes processing after telmod receives a protocol sequence which it does
40  * not process itself.  If data is attached to this ioctl, telmod inserts it
41  * at the head of the read queue.

43  * TEL_IOC_MODE: Establish the mode for data processing.  Currently binary
44  * input and output are the only modes supported.
45  *
46  * TEL_IOC_GETBLK: When telmod is not enabled, this ioctl requests that
47  * the next input message from the network to be processed is forwarded
48  * through the mux to the daemon.
