+.SH NAME
+tmscp \- DEC TMSCP magtape interface
+.SH SYNOPSIS
+.B "controller tmscp0 at uba? csr 0174500 vector tmscpintr"
+.br
+.B "tape tms0 at tmscp0 drive 0"
+.SH DESCRIPTION
+Tape controllers compatible with the DEC
+Tape Mass Storage Control Protocol (TMSCP) architecture
+such as the TU81 and the TK50
+provide a standard tape drive interface 
+as described in
+.IR mtio (4).
+The controller communicates with the host through a packet
+oriented protocol.
+Consult the file
+.IR < vax/tmscp.h >
+for a detailed 
+description of this protocol.
+.SH DIAGNOSTICS
+.BR "tmscp controller failed to init" .
+The controller initialization procedure failed.
+This probably indicates a hardware problem.
+.PP
+.BR "tmscp%d: sa 0%o, state %d" .
+(Additional status information given after a hard I/O error.)
+The values of the controller status register and the internal
+driver state are printed.
+.PP
+.BR "tmscp%d: random interrupt ignored" .
+An unexpected interrupt was received (e.g. when no i/o was
+pending).  The interrupt is ignored.
+.PP
+.BR "tmscp%d:  interrupt in unknown state %d ignored" .
+An interrupt was received when the driver was in an unknown
+internal state.  Indicates a hardware problem or a driver bug.
+.PP
+.BR "tmscp%d:  fatal error (0%o)" .
+The controller detected a ``fatal error'' in the status returned
+to the host.  The contents of the status register are displayed.
+.PP
+.BR OFFLINE .
+(Additional status information given after a hard I/O error.)
+A hard I/O error occurred because the drive was not on-line.
+.PP
+The following errors are interpretations of TMSCP error messages
+returned by the controller to the host.
+Each is preceded by either
+.B "tmscp%d: hard error"
+or
+.BR "tmscp%d: soft error" .
+.PP
+.BR "controller error, event 0%o" .
+.PP
+.BR "host memory access error, event 0%o, addr 0%o" .
+.PP
+.BR "tape transfer error, unit %d, grp 0x%x, event 0%o" .
+.PP
+.BR "STI error, unit %d, event 0%o" .
+.PP
+.BR "STI Drive Error Log, unit %d, event 0%o" .
+.PP
+.BR "STI Formatter Error Log, unit %d, event 0%o" .
+.PP
+.BR "unknown error, unit %d, format 0%o, event 0%o" .
