20: .SH DESCRIPTION
21: The \fIvtd\fR server implements the responder side of
22: a remote login service based on the ISO Virtual Terminal (VT)
23: standard and the VT TELNET profile from the NIST OSI Workshop
24: Implementor's Agreements.
25: .SH OPTIONS
26: .TP
27: .B -d 0-7
28: Set the level of debug output from 0, meaning none, to 7, which is
29: the most verbose.
30: .TP
31: .B -F logfile
32: Sets the VT logfile.
33: Note that the pathname of this file is interpreted relatively to the
34: ISODE logging area.
35: To have tracing information written to a file in the current
36: directory,
37: start the filename with \*(lq./\*(rq.

58: Parts of this program are based on the \fItelnet\fR(1c) program supplied with
59: Berkeley UNIX.
60: .SH BUGS
61: \fIvt\fR and \fIvtd\fR need to be brought up to date with BSD 4.3(4?)
62: TELNET.
63: .PP
64: The encodings of the VT PDUs may need to be updated when
65: the International Standard version of ISO 9041 is available.
66: .PP
67: When an association is established,
68: a possible bug in the PTY driver on systems derived from Berkeley UNIX
69: may cause the \*(lqlogin:\*(rq prompt to be lost.
70: The \fIlogin\fR program is still running,
71: the user need only type-in the username or hit RETURN for another prompt.
72: .PP
73: Due to a possible bug in the PTY driver on systems derived from Berkeley UNIX,
74: it is important that the responder always run detached from a
75: controlling terminal.
76: Since the repsonder is invoked from \fItsapd\fR\0(8c),
77: this requirement is passed on to the \fItsapd\fR program.
78: Thus,
79: when running the VT responder,
80: it is \fBcritical\fR that \fItsapd\fR be started under
81: \fI/etc/rc.local\fR or in \*(lqbackground\*(rq mode, e.g.,
82: .sp
83: .in +.5i
84: .nf
85: # \*(SDtsapd >& /dev/null
86: .fi
87: .in -.5i
88: .sp
89: which will cause the daemon to automatically detach.
