13 The ct utility dials the telephone number of a modem that is attached
14 to a terminal and spawns a login process to that terminal. The telno is
15 a telephone number, with equal signs for secondary dial tones and minus
16 signs for delays at appropriate places. (The set of legal characters
17 for telno is 0 through 9, -, =, *, and #. The maximum length telno is
18 31 characters). If more than one telephone number is specified, ct will
19 try each in succession until one answers; this is useful for specifying
20 alternate dialing paths.
21
22
23 ct will try each line listed in the file /etc/uucp/Devices until it
24 finds an available line with appropriate attributes, or runs out of
25 entries.

28 After the user on the destination terminal logs out, there are two
29 things that could occur depending on what type of port monitor is moni‐
30 toring the port. In the case of no port monitor, ct prompts: Reconnect?
31 If the response begins with the letter n, the line will be dropped;
32 otherwise, ttymon will be started again and the login: prompt will be
33 printed. In the second case, where a port monitor is monitoring the
34 port, the port monitor reissues the login: prompt.
35
36
37 The user should log out properly before disconnecting.
38
40 The following options are supported:
41
42 -h Normally, ct will hang up the current line so that it can
43 be used to answer the incoming call. The -h option will
44 prevent this action. The -h option will also wait for the
45 termination of the specified ct process before returning
46 control to the user's terminal.
47
48
49 -sspeed The data rate may be set with the -s option. speed is
50 expressed in baud rates. The default baud rate is 1200.
51
52
53 -v If the -v (verbose) option is used, ct will send a running
54 narrative to the standard error output stream.
55
56
57 -wn If there are no free lines ct will ask if it should wait,
58 and for how many minutes, before it gives up. ct will con‐
59 tinue to try to open the dialers at one-minute intervals
60 until the specified limit is exceeded. This dialogue may be
61 overridden by specifying the -wn option. n is the maximum
62 number of minutes that ct is to wait for a line.
63
64
65 -xn This option is used for debugging; it produces a detailed
66 output of the program execution on stderr. n is a single
67 number between 0 and 9. As n increases to 9, more detailed
68 debugging information is given.

94 The ct program will not work with a DATAKIT Multiplex interface.

97 For a shared port, one used for both dial-in and dial-out, the ttymon
98 program running on the line must have the -r and -b options specified
99 (see ttymon(1M)).
