Bookmark This site


The file "digi_ned.mes" contains auto-reply strings for simple text reponses. Here you can define aditional queries to complement with build in queries. The only queries which are build-in are the queries which return a runtime-dependent reply string. All queries which have static textst are defined in this file.

  • %d will be replaced by the digipeater call
  • %o will be replaced by the digi owner call
  • %v will be replaced by the DIGI_NED version
  • %b will be replaced by the DIGI_NED boot-time
  • %p will be replaced by the number of active ports
  • %q will be replaced by the complete query as received (lowercase). Also single quotes are removed so the variable can be enclosed with single quotes to avoid unwanted redirecton when the ">" character is used in a query.
  • %x will be replaced by the full packet containing the query.
    Note that the originator call has been replaced by the real-originator when there is a 3rd party header.
    This variable can be used when you start a program with a query and you want to retrieve specific information, like the sender of the query for example. In the packet the control-characters are replaced by a "." (except those used in MIC-E). Single quotes are also replaced by a "." so for execution from a query the whole %x variable can be enclosed in single quotes to avoid problems with redirect characters in the received packet query and more such problems.

Syntax is simple, each query starts with an ?, the lines following it up to the next query is the response, empty lines and lines starting with '#' are ignored. Multiple lines are allowed.

The first character of each line is interpreted and determines how the answer is send back. These characters are the following:

  • ';': Lines stating with ';' are transmitted as "objects".
  • ')': Lines with ')' are transmitted as "items".
  • ':': Lines with ':' are transmitted as messages but this time exactly the way they are written down, so these lines includes the address (See ?BLN query below for a bulletin example).
  • '!': These lines do not return anything but start runs a program instead. During the run of the program the digi is inactive so keep these programs short. For an example see the "?whois" query.
  • '!!':This is just like the '!' above. Unlike the '!' above you need to be owner of the digi to have the program executed however. For an example see the ?sysop example query the digi is inactive so keep these programs short.
  • '>': The data to return is read from a file. This can be the output of a program for example. The contents of the gile is send back as a normal message. The file may contain multiple lines.

The '\' character can be used as 'escape' if you want your message to start with '?', '#', ')', ':', '!' or '>'. If you want the message to start with a '\' character then use "\\".

Aliasses for the same query can be specified, for example:

?help|?h responds to query "?help" and shortcut "?h".

Also wildcards can be used. ?h* for example matches all queries thatstart with ?h. Be carefull with this not to create ambiguity which will be confusing!

Wild cards are:

  • * Matches any 0 or more character(s).
  • ? Matches any 1 character.
  • @ Matches any alpha character.
  • ! Matches any digit.

When '*' is used and additional characters follow after the '*' then characters in the received query will be skipped until a match is found again, from that point checking will proceed.


Using "s*on" will match "station" but not "stat"; after the '*' the code will look for an 'o' and proceed checking from there. In case of "stat" the 'o' is not found and the match fails. When matching with "stations" the match also fails since the part from the 'o' until the end is not the same. "s*on*" will match both "station" and "stations". For an example look at the "?whois" query below that uses a wildcard to match any argument following whois.

On all queries the ? is optional, so you can also use "help" and "h" with the above example (same applies to the build-in queries like "mheard" etc). Query strings can be mixed case (doesn't matter), the user can use mixed case when he queries DIGI_NED.

The query that only consists of one '?' is a special one since this the response for this query is also the default reply on any query that doesn't match.

Lines, query lines and answers, can be up to 67 characters,

longer lines will be truncated In this example file I allligned the messages to nicely fit on the 12 character THD7 screen.

It is strongly recommended to keep these basic entries like ?help ?digi, ?voice, ?bbs etc. so new people on the move which enter your system can guess what to expect without having to dig through the help first. I take a risk here by allowing you to make changes, please think about the mobile and stations not familiar with your neigborhood and area. I think they will appriciate to find the commands ?voice and ?net to work to make initial contact with you!

A bulletin is sent!

:pe1dnn-7 :Hello Henk!

# This is powerfull! An external program can be run on a query and its
# output can be returned to the caller. Here is an example "whois" server
# which is only one of the many posibilities!
# With "%q" the original query string can be passed to the program
# note that single quotes are replaced by "." characters so the %q
# variable can be enclosed in quotes.
# Whois example for Linux
#?whois *
#!./Sample.lnx/whois.sh '%q'
#!/bin/rm ./Sample.lnx/whois.out

# Whois example for DOS
?whois *
!.\Sample.dos\whois.bat '%q'
!del .\Sample.dos\whois.out > nul

# Echo example
Echo: '%x'

# Sample of a sysop only command, command to execute starts with double !!
!!echo Ok, you are Sysop > tmpxyz
!rm tmpxyz
