                     28: .SH DESCRIPTION
                     29: The 
                     30: .I hdh
                     31: device provides an HDLC Host (HDH)
                     32: interface to an IMP.  It is normally used when participating
                     33: in the DARPA Internet.  The controller itself is not accessible
                     34: to users, but instead provides the hardware support to the IMP
                     35: interface described in
                     36: .IR imp (4).
                     37: When configuring, the 
                     38: .I imp
                     39: pseudo-device must also be included.
                     40: .SH DIAGNOSTICS
                     41: .BR "hdh%d: not alive" .
                     42: The initialization routine was entered even though the device
                     43: did not autoconfigure.  This indicates a system problem.
                     44: .PP
                     45: .BR "hdh%d: cannot get chan %d uba resources" .
                     46: Insufficient UNIBUS resources existed to initialize the device.
                     47: This is likely to be a shortage of UNIBUS mapping registers.
                     48: .PP
                     49: .BR "hdh%d: LINE UP" .
                     50: This indicates that both the HDLC and HDH protocols have declared the
                     51: link to the IMP alive.
                     52: .PP
                     53: .BR "hdh%d: LINE DOWN" .
                     54: This indicates that the link to the IMP has died.
                     55: .PP
                     56: .BR "hdh%d: HOST SEQUENCE ERROR"

                     63: .br
                     64: These errors indicate that an HDH protocol error has been detected.
                     65: .PP
                     66: .BR "hdh%d: cannot get supervisor cmnd buffer" .
                     67: This error indicates that an
                     68: .I mbuf
                     69: could not be allocated to send a command to the IF-11/HDH.
