An asynchronous ! 14: communication port connects each user to the system, normally by ! 15: a terminal or a modem attached to the port. The system com- ! 16: municates with the port by means of a character special file in ! 17: directory /dev, such as /ddeevv/ccoomm33rr or /ddeevv/ccoomm22ll. ! 18: ! 19: The COHERENT system will not allow a user to log in on a port un- ! 20: til the system creates a login process for the port. The enable ! 21: command tells the system to create a login process for each given ! 22: port. For example, the command ! 23: ! 24: ! 25: /etc/enable com1r ! 26: ! 27: ! 28: enables port /dev/com1r. ! 29: ! 30: enable changes the entry for each given port in the terminal ! 31: characteristics file /etc/ttys. The baud rate specified in ! 32: /etc/ttys must be the appropriate baud rate for the terminal or ! 33: modem connected to the port. See the Lexicon entry for ttys for ! 34: more information. ! 35: ! 36: The command disable disables a port. The command ttystat checks ! 37: whether a port is enabled or disabled. ! 38: ! 39: ***** Files ***** ! 40: ! 41: /eettcc/ttttyyss -- Terminal characteristics file ! 42: /ddeevv/ccoomm* -- Devices serial ports ! 43: ! 44: ***** See Also ***** ! 45: ! 46: com, commands, disable, getty, login, ttys, ttystat ! 47: ! 48: ***** Diagnostics ***** ! 49: ! 50: enable normally returns one if it enables the port successfully ! 51: and zero if not. If more than one port is specified, enable ! 52: returns the success or failure status of the last port it finds. ! 53: It returns -1 if it cannot find any given port. An exit status ! 54: of -2 indicates an error. ! 55: ! 56: ***** Notes ***** ! 57: ! 58: It is not recommended that you attempt to enable a port that is ! 59: already enabled. To make sure, run /etc/disable before running ! 60: /etc/enable. ! 61: ! 62: ! 63: ! 64: COHERENT Lexicon Page 1 ! 65: ! 66: ! 67: ! 68: ! 69: enable Command enable ! 70: ! 71: ! 72: ! 73: Only the superuser root can execute enable. ! 74: ! 75: ! 76: ! 77: ! 78: ! 79: ! 80: ! 81: ! 82: ! 83: ! 84: ! 85: ! 86: ! 87: ! 88: ! 89: ! 90: ! 91: ! 92: ! 93: ! 94: ! 95: ! 96: ! 97: ! 98: ! 99: ! 100: ! 101: ! 102: ! 103: ! 104: ! 105: ! 106: ! 107: ! 108: ! 109: ! 110: ! 111: ! 112: ! 113: ! 114: ! 115: ! 116: ! 117: ! 118: ! 119: ! 120: ! 121: ! 122: ! 123: ! 124: ! 125: ! 126: ! 127: ! 128: ! 129: ! 130: COHERENT Lexicon Page 2 ! 131: ! 132:
