 3 Syntax as a command:  ctl_term arg
 4 
 5 
 6 Function:  applies only to a control terminal (if attached).  It allows
 7 the operator to specify the format of printed output.
 8 
 9 One of the primary functions of the control terminal is to print
10 information about each request processed, to aid in separating the
11 output, and to ensure proper accountability of output generated by the
12 driver.  It is possible for the site to use preprinted forms for this
13 purpose.  (for information on preprinted forms, see the Multics System
14 Maintenance Procedures manual, Order No.  AM81.)  In this case,
15 alignment of the data on the form is very important.  Generally a
16 terminal that supports vertical tab and form feed control characters is
17 used to ensure alignment.  However, this command allows the operator to
18 request that the software simulate the action of form feed control
19 characters if the terminal does not provide this hardware support.

22 Arguments:
23    where arg falls into one of two classes:  general control or
24    simulation control (some arguments require an additional value to
25    define the requested action).
26 
27    general control
28    form_type STR
29       specifies the format program to be used to format the data
30       printed on the control terminal.  If STR is "default", the
31       form_type is set to the default format.
32    detach
33       discontinues the use of the control terminal.  This argument is
34       restricted to the master terminal and is not reversible unless
35       the reinit command is given.
36 
37 
38    simulation control
39    simulate
40       sets the driver to simulate form feeds by software.  (This
41       argument is not reversible even by the reinit command.)
42    page_length N
43       sets the number of lines per logical page to N.  This controls
44       the forward spacing needed to go to the top of the form.
45    aligned
46       indicates that the forms are aligned for the purpose of form feed
47       control.  (A sample form can be printed by the sample_form
48       command.)
