- NAME
- UUCico
-
- SYNOPSIS
- UUCico -D[EVICE] device -U[NIT] unit -Getty -w -r1 -xn -Xn -xx -h0
- -o -[s/S]system -e -s -7 -p # -pri -d0 -t<timeout> -T<timeout>
-
- DESCRIPTION
- UUCico is the basis for UUCP. It can be run either from a
- GETTY when somebody logs into the Amiga, or it can be run
- from DCRON or manually to originate connections.
-
- Some options to UUCico are now outdated and should not be
- used. Specifically, earlier distributions did not have a
- GETTY and UUCICO had to deal with waiting for connections
- itself.
-
- Either way, the final result is a connection between your
- machine and some remote machine. UUCICO will retrieve any
- queued work on the remote machine and send any queued work on
- your machine. These work files are located in UUCP:SPOOL.
-
- The term 'work' refers to items queued by other programs,
- such as PNEWS and MAIL. These programs create files in
- UUCP:SPOOL that inform UUCICO what to do with them and where
- to send them to. On the flip side, when UUCICO receives a
- work file it will write it to UUCP:SPOOL then run UUXQT.
-
- UUXQT scans received files and determines how to break them
- up (for example, append them to the appropriate mail box or
- news directory). The control files in UUCP:SPOOL contain a
- line indicating the appropriate program required to unpack
- the files. UUXQT reads this line and runs the proper
- unpacker (RMAIL, RNEWS, or CUNBATCH).
-
- LOCKING
-
- UUCico locks the serial port in the same manner Getty does, but
- doing the equivalent of the UUCP:C/LOCKSERIAL command before
- openning it. Thus, uucico's will never bump into each other
- on the port. Any terminal program you run should lock the
- serial port as well. This is done by running the terminal
- program via UUCP:C/LOCKSERIAL with the appropriate arguments,
- see the manual pages for GETTY and LOCKSERIAL for more information
-
-
- GENERAL OPTIONS
-
- (*)'d Options are supplied automatically on Getty Initiated
- connections
-
- (*) -D devicename Default is serial.device (space is required)
- (*) -U unitnumber Default is 0 (space is optional)
- -xn Set log level for us and for remote system
- -Xn Set log level but do not tell remote system
- about it.
-
- -xx Debug handshake to stdout (but not once connection
- is established). Useful for debugging L.Sys
- send-expect stuff.
-
- -h0 Ignore Carrier Detect.
-
- -b BATCH news before anything else
-
- -7 Set 7WIRE mode for serial connections
- (i.e. hardware handshaking)
-
- -p #
-
- -pri UUCico ups its priority by 1 during transfer,
- then downs it by 1 to run uuxqt. (i.e. +1
- during transer, -1 for uuxqt)
-
- -d0 IGNORE DTR switch forces UUCico to use the
- +++ sequence to disconnect instead of dropping
- DTR. This is a workaround for a possible
- bug in the serial device for those who
- experience crashes when UUCico tries to
- disconnect.
-
- -n[size] Set protocol window size. If size is not
- specified, a window size of 1 is forced. The
- default (-n option not specified) it a
- window size of 7.
-
- Sometimes it is necessary to reduce the window
- size to 3 or 4 when connecting to heavily
- loaded UNIX systems.
-
- -t<timeout> Set GIO protocol timeout before packet retry.
- Default is 5. In many cases this can cause
- long no-activity delays due to small glitches
- when, in fact, the receiving host is not loaded
- down. Setting the timeout to 1 generally fixes
- this.
-
- -T<timeout> Set timeout for send-expect strings, default
- is 15 seconds.
-
- -P<segsize> Set segment size, in powers of two where a
- segment size of 2 == 64 bytes. The maximum
- segment size is 9 (2048 bytes??).
-
- This option should be used only by EXPERIENCED
- UUCP users. Larger is not necessarily better
- since all packets are fixed length.
-
- GETTY INITIATED OPTIONS
-
- (*) -Getty Tells UUCICO that it was started from a Getty.
-
- MANUAL POLL OPTIONS
-
- -ssystem Poll (call-up) the specified system
-
- -Ssystem Same as -s but ignore time restrictions
- (note, currently time restrictions are
- ignored anyway)
-
- -r1 Call all systems we have pending work for
-
- -r1 -ssystem Call this specific system if we have pending
- work.
-
- -o Tells UUCICO to not search for a CONNECT
- message when carrier is detected (hardwired
- configuration)
-
- OBSOLETE OPTIONS (WAIT MODE OPTIONS) DO NOT USE IF YOU CAN HELP IT
-
- -w Tells UUCICO to wait for one or more
- connections (depending on -e) AFTER having
- previously polled one or more systems
- (-r, -s, -S).
-
-
- -e Tells UUCICO to loop forever waiting for
- connections.
-
- <nooptions> If UUCICO is run without either -Getty,
- -s, or -r, it will wait for a single
- connection.
-
- TIMELOG FORMAT
- UUcico automatically appends an entry to UUSPOOL:TimeLog in
- the following format:
-
- dd-mmm-yy mm:ss mm:ss in=nnnnn out=nnnnn <system_name>
-
- The date, then two on-line times. The first is the connect time
- from carrier detect, the second is connect time from send-expect
- success. Use whichever one is appropriate for bill calculations.
- Following that is the number of data bytes received (total of
- received file sizes) and the number of data bytes sent (total of
- transmitted file sizes). These numbers do not reflect additional
- overhead used by the G protocol (messages, acks, packet overhead,
- or retries).
