25: .SH DESCRIPTION
26: .I Con
27: connects to the computer whose network address is
28: .I machine
29: and logs in if possible.
30: Standard input and output go to the local machine.
31: Option
32: .B -l
33: prevents automatic login; a normal login dialog ensues.
34: .PP
35: The quit signal (control-\e) is a local escape.
36: It prompts with the local machine name and
37: .BR >> .
38: Legitimate responses to the prompt are
39: .TP \w'\fL!\fIcommand\ \ 'u
40: .B i
41: Send a quit [sic] signal to the remote machine.
42: .PD0
43: .TP
44: .BR q , " x" ", or " .
45: Exit.
46: .TP
47: .B b
48: Send a break.
49: .TP
50: .BI ! command
51: Execute
52: .I command
53: locally.
54: .PD
55: .PP
56: .I Rx
57: executes one shell command
58: on the remote machine as if logged in there,
59: but with local standard input and output.
60: Unquoted shell metacharacters in the command
61: are interpreted
62: locally, quoted ones remotely.
63: The assignment
64: .B REXEC=1
65: appears in the remote environment.
66: With no arguments,
67: .I rx
68: just diagnoses availability.
69: Option
70: .B -n
71: ignores sporadic end-of-file indications on a
72: sick network.
73: .PP
74: Network addresses for both
75: .I con
76: and
77: .I rx
78: have the form
79: .IB network ! host
80: or simply
81: .I host.
82: Supported networks are
83: .L dk
84: (Datakit) and
85: .L tcp
86: (TCP/IP, usually Ethernet).
87: .PP
88: Directory
89: .F /usr/bin/m
90: contains machine names as commands:
91: .BI /usr/bin/m/ machine
92: with no argument runs an appropriate flavor of
93: .I con
94: for the named
95: .I machine.
96: If given arguments,
97: .BI /usr/bin/m/ machine
98: runs
99: .I rx
100: with those arguments.
101: If
102: .F /usr/bin/m
103: is in the
104: .IR sh (1)
105: search path,
106: the names become commands for navigating the
107: local cluster.
108: .SH EXAMPLES

150: .SH BUGS
151: The remote standard error and standard output are combined
152: and go inseparably to the local standard output.
153: .br
154: Under
155: .I rx,
156: a program
157: that should behave specially towards terminals may not:
158: .IR sh (1)
159: will not prompt,
160: .IR vi (1)
161: will not manage the screen, etc.
162: .I Nrx
163: (see
164: .IR dcon (1))
165: avoids this trouble, but has others of its own.
166: .br
167: .I Con
168: and
169: .I rx
170: may not guess the right kind of connection.
171: In case of trouble, try the programs in
172: .IR dcon (1).
173: .br
174: The names in
175: .F /usr/bin/m
176: are conventions, not actual network addresses.
