12: The initialization process init invokes getty for each terminal
13: indicated in the file /etc/ttys. getty tries to read a user name
14: from the terminal which is the standard input, adapting its mode
15: settings accordingly. Then getty invokes login with the name
16: read. This process may set delays, mapping of upper to lower
17: case, speed, and whether the terminal normally uses carriage
18: return or linefeed to terminate input.
19:
20: If the terminal baud rate is wrong, the login message printed by
21: getty will appear garbled. If the specified type indicates vari-
22: able speeds, as described below, hitting BREAK will try the next
23: speed.
24:
25: init passes the third character in a line of the file /etc/ttys
26: as the type argument to getty. type conveys information about
27: the terminal port. An upper-case letter in the range A to S
28: specifies a hard-wired baud rate, as indicated in the header file
29: <sgtty.h>. Other characters specify a range of speeds suitable
30: to a dial-in modem. The following variable-speed settings are
31: recognized:
32:
33: 00 Cycles through speeds 300, 1200, 150, and 110 baud, in that
34: order. This is a good default setting for dial-in ports.
35:
36: - Teletype model 33, fixed at 110 baud.
37:
38: 11 Teletype model 37, fixed at 150 baud.
39:
40: 22 9600 baud with delays (e.g., Tektronix 4104).
41:
42: 33 Cycles between 2400, 1200, and 300 baud. This is used with
43: 2400-bps modems.
44:
45: 44 DECwriter (LA36) with delays.
46:
47: 55 Like 3, but starts at 300 baud.
48:
49: getty recognizes the following fixed-speed settings, for hard-
50: wired terminals:
51:
52: AA 50 baud
53: BB 75 baud
54: CC 110 baud
55: DD 134 baud
