/*
** This command is used to display the versions of the various
** MINIMON 29K modules. First the version of the host code and
** its date is printed from the global data structure "host_config".
** Next the montip version field and date is printed from
** the VERSION_SPACE UDIRead call. This is an ascii zero terminated
** field of ** less than 11 characters.
** Next the "version" field in the "target_config" data structure is
** printed. This "version field is encoded as follows:
**
** Bits 0 - 7: Target debug core version
** Bits 8 - 15: Configuration version
** Bits 16 - 23: Message system version
** Bits 24 - 31: Communication driver version
**
** Each eight bit field is further broken up into two four bit
** fields. The first four bits is the "release" number, the
** second is the "version" number. This is typically printed
** as <version>.<release>. i.e. version=2, release=6 is
** printed as "2.6".
**

/*
** The os version number is coded into the eighth word of the
**configuration message. It is in the lower 8 bits.
** Bits 0 - 7: OS version
