This file holds the definitions of all the communications protocols known to the kernel.  A protocol has executable MUMPS code for
sending, receiving, opening, and closing a link.  This file is not to be touched by anyone not intimately knowledgeable with the
workings of the networked MailMan.

              HELP-PROMPT:      ANSWER MUST BE 1-200 CHARACTERS IN LENGTH 
              DESCRIPTION:      The executable MUMPS code which will open the communication channel, setting the variable IO to the
                                proper value.

                                XMNO220=1 will stop MailMan from issuing its second (and mandatory when talking to another MailMan
                                system, but fatal when talking to non-MailMan SMTP messaging systems) 220 'ready' when the receiver
                                is indicating it is on the line and ready to receive.  
                                 
                                XMD="D" causes MailMan to echo on the principle device the entire transmission script.
