+.SH NAME
+mdsms \- send SMSes through MobilDock
+
+.SH SYNOPSIS
+.B mdsms
+.RB [ "-c <cfgfile>" ]
+.RB [ "-d <device>" ]
+.RB [ "-l <lockfile>" ]
+.RB [ "-s <smsc #>" ]
+.RB [ "-t <msec>" ]
+.RB [ "-T <msec>" ]
+.RB [ "\-vhV" ]
+.RB [ "<dest. phone>" ]
+.RB [ "<msg text>" ]
+
+.SH DESCRIPTION
+Program sends one SMS message through MobilDock device.
+
+.SH OPTIONS
+.TP
+.BR -c | --config\ < cfgfile >
+Process recursively this file and read all options from it. See the section
+.B CONFIGURATION
+for more information.
+.TP
+.BR -d | --device\ < device >
+Specify serial device to communicate with MobilDock. If only bare name is
+specified, "\fB/dev/\fP" is prepended automatically. This device name is used
+subsequently with
+.BR -l | --lockfile
+option, see below.
+.TP
+.BR -l | --lockfile\ < lockfile >
+Prior to accessing serial device specified above the lockfile should be
+acquired for correct concurrent processes behaviour. Although this name
+can be given as direct filename more common method is to use pattern
+with embedded "\fB%s\fP" where this mark is replaced by actual basename
+(last component of pathname with all preceding directory names stripped)
+of serial device used.
+Default name for lockfile is ~\fB DEF_LOCKFILE \fP~.
+.TP
+.BR -s | --smsc\ < smsc\ # >
+Specify custom SMS center number. If not specified (or overriden as empty
+string by \fB-s ""\fP)
+.B mdsms
+asks by "\fBAT+CSCA?\fP"
+Siemens A1 for its default SMS center. Situation with undeterminable SMS center
+is unrecoverable and casues immediate fail. It is a common practice to use
+plus sign ("\fB+\fP") to indicate international number type.
+Known SMS centers as of May 1999:
+.RS
+.TP
+.BR "CZ Paegas " ( "230 01" "): " +420603052000
+.TP
+.BR "CZ EuroTel " ( "230 02" "): " +420602909909
+.RE
+.TP
+.BR -t | --chartime\ < msec >
+Although the fixed used baudrate of
+.B 19200
+is pretty low, MobilDock/Siemens A1 couple
+.RB "aren't"
+able to accept steady
+stream of data at this speed. Even the used XON/XOFF handshaking is just not
+enough. The only possible workaround is to slowdown the communication by
+waiting a bit after character sent to give relax time to these devices.
+When full rate communication was used, occasional longer SMS data corruption
+was observed. Argument is given in milliseconds and its default value is
+.BR DEF_CHARTIME ms.
+.TP
+.BR -T | --cmdtime\ < msec >
+This delay is given before sending any
+.B AT-style
+command to MobilDock/Siemens A1.
+Its primary purpose is to let any previous entered commands to finish and
+to clear any input before actually sending our own command. Also all Siemens
+devices are known that they strongly dislike fast edge-to-edge communication
+and to satisfy these requirements this delay was considered as the best
+approach. The default value is
+.BR DEF_CMDTIME ms.
+.TP
+.BR -v | --verbose
+Increase verbosity level by one. Currently the maximum defined level is
+.BR 3 ,
+the default value is
+.BR 0 .
+.TP
+.BR -h | --help
+Give short parameters description to
+.I stderr
+(standard error output stream).
+.TP
+.BR -v | --version
+Print the version number and exit.
+.TP
+.RB < "dest. phone" >
+This mandatory parameter specifies the telephone number of the recipient
+of SMS message. International prefix character plus
+.RB ( + )
+is supported the national mode without plus
+.RB ( + )
+prefix is supported and the meaning is specific to the GSM operator currently
+being roamed in (NOT the native
+.RB "'home'"
+operator of the SIM card!).
+This number can be made default in system configuration files, see below
+for section
+.BR CONFIGURATION .
+.TP
+.RB < "msg text" >
+Here you write the exact body of the message. This parameter should be
+specified only as one component, although if more found they are concatenated
+with separating space (" "). But this practice is discouraged as
+your shell will probably remove any multiple spaces found and also other
+metacharacters may be incorrectly interpreted. To prevent any escaping
+mess, you may prefer to omit this parameter and the the message text is
+then read from
+.I stdin
+(standard input stream).
+
+.SH CONFIGURATION
+.B mdsms
+reads ~\fB CONFIG_MAIN \fP~ followed by ~\fB$HOME CONFIG_HOME \fP~
+configuration files. The content of these files (and also any file read by
+.BR -c | --config
+option)
+has the usual
+.BR getopt (3)
+syntax with dashes. Newlines are taken as whitespace, both double ("\fB~\fP")
+and single ("\fB'\fP")
+quoting is supported. Embedded quote characters can be escaped by backslash
+("\fB\\\fP").
+Arguments are processes in order as specified in configuration files and
+finally the command-line of the program itself, overriding any previous
+values. Although the order of
+.BR -c | --config
+options on one line is preserved the first file is read AFTER all of the
+current options are processed. Recursive use of
+.B -c
+is permitted and the files are read in LIFO (Last-In First-Out, AKA stack)
+order. You should use "\fB-v -v\fP"
+to see details of option processing with more complex configuration setups.
+
+.SH OPERATION
+Upon startup
+.B mdsms
+locks the port (see option
+.BR -l | --lockfile
+for details) and opens the serial device with hardcoded parameters of
+19200 baud, software handshaking (XON/XOFF style), 8 bits, no parity.
+Then issues the following commands:
+.TP
+.BR AT <CTRL-Z>
+.B AT
+is used to fool MobilDock and pass the following
+.B <CTRL-Z>
+(ascii decimal code 26) character to Siemens A1 and break it from eventual
+.B AT+CMGS
+mode in which it may errorneously remain from previous sessions.
+.TP
+.B AT
+Test the responsiveness of Siemens A1.
+.TP
+\fBAT+CSCA="\fPsmc # from user\fB"\fP
+This command is omitted if
+.B "smsc #"
+is not specified by user (or specified/overriden as empty string \fB""\fP
+.TP
+\fBAT+CSCA?\fP
+Query the currently set SMC center number to include it later to the
+header of SMS PDU format where it is required. If \fBAT+CSCA="\fP...\fB"\fP
+was issued before, this number should match it but no sanity checks are
+currently do so.
+.TP
+\fBAT+CMGF=0\fP
+Set the default SMS message format to PDU type. Currently Siemens A1
+.RB "doesn't"
+support any other SMS format anyway.
+.TP
+\fBAT+CMGS=\fP# chars
+This command physically sends the message and the resulting "\fB+CMGS:\fP" output
+is catched and returned as
+.B MR
+(message reference) number to the user.
+.TP
+\fBAT\fP
+Check that Siemens A1 survived the sending of the message.
