3 Pager calling pre-filter

    Here we introduce a pre-processing program which converts Japanese to
    codes recognized by a pager.  Please do not ask me the detail around
    between an operating system and a modem. The details depend on your
    pager, modems and so on.

    3.1	euc2jiskuten.pl

       ftp://ftp.iij.ad.jp/pub/IIJ/dist/fukachan/calling-pager/

    We need to translate Japanese to JIS Kuten codes for sending the mail
    content to a pager.

    We translate the mail content to EUC codes, and then to JIS Kuten
    codes by euc2jiskuten.pl. You have only to send JIS Kuten codes to
    a pager.

    3.2	How to call pager through FML

    1	prepare calling modem program (call it "modem2pager").

    2	Configure $START_HOOK as the following example:

    	open(PAGER, "| euc2jiskuten.pl | modem2pager");
    	print PAGER $Envelope{'Body'}:
    	close(PAGER);
    	$DO_NOTHING = 1;

    FML sends the mail body to euc2jiskuten.pl and then to modem2pager.
    Modem2pager should queue and send it via e.g. /dev/tty01 to a modem.
    You must tune queuing codes of modem2pager, which must be difficult.
