Mgetty is a ``smart'' getty replacement, designed to be used with hayes compatible data and data/fax modems. Mgetty knows about modem initialization, manual modem answering (so your modem doesn't answer if the machine isn't ready), UUCP locking (so you can use the same device for dial-in and dial-out). Mgetty provides very extensive logging facilities.
Tells mgetty to leave ''
Use the given level of verbosity for logging - 0 means no logging, 9 is really noisy. The log file is usually /tmp/log_mg.
Set the port speed to use, e.g.
Tells mgetty that it is running on a direct line. UUCP locking is done, but no modem initialization whatsoever.
Use the given string to prompt users for their login names. Various tokens are allowed in this string. These tokens are: @ for the system name, n, r, g, v, f, t for newline, carriage return, bell, vertical tab, form feed, and tab, respectively. P and L will expand to the tty name (
The default prompt is specified at compile time.
Tells mgetty to pick up the phone after the #th RING. Default is 1.
Tells mgetty to go into ''
I do not really recommend using this, better get a second phone line for the modem.
Tells mgetty that the modem is to be treated as a DATA modem, no fax initalization is attempted.
Tells mgetty that DATA calls are not allowed and the modem should be set to Fax-Only.
Tells mgetty how to treat the modem. Possible values for ''
If a call comes in and requests fax polling, mgetty will send the named file. Note: not all fax modems support poll sending.
Use the given fax station ID for fax identification. Not used for data modems.
Open the port in blocking mode. Best used in combination with mgetty is called as getty.'' You may want to use this if you want to make use of the two-device / kernel-locking scheme of the Linux and SunOS operating systems (/dev/ttyS.. and /dev/cua..). I do not recommend it, it's just include for completeness, and to be able to use mgetty as a full-featured getty replacement.
Use autobauding. That is, after a connection is made, mgetty parses the ''
-m 'expect send ...'
Main configuration file.
controls whether (and when) mgetty should call some other program for user login instead of /bin/login. How this is done is explained in this file.
controls acceptance/denial of incoming calls based on the caller's number. Available only if you have
controls whether mgetty should pick up the phone upon incoming calls. If the file exists, calls are completely ignored. You can use this, for example, to stop mgetty during day time, and let it pick up at night only, by creating and removing /etc/nologin.ttyxx via the cron program at the appropriate time.
will be printed after a connection is established, and before the with the '-i' option.
If mgetty doesn't work the way it should, the main source of diagnostic data is the log file. It can be found in ''
Not all of mgetty configuration can be done at run-time yet. Things like flow control and file paths (log file / lock file) have to be configured by changing the source and recompiling.
