HP Guardian Errors Manual page 264

Format The operating system sends the process the following message, provided the process has
opened its $RECEIVE file to receive file management system messages either by setting the
FILE_OPEN_ procedure parameter options.<15>to 0 or the OPEN procedure parameter flags.<1>to
1:
sysmsg[0] = -104
sysmsg[1] = tapedisposition parameter to FILE_CLOSE_
Response If the application is tracking openers, the receiver should call FILE_GETRECEIVEINFO_
to obtain the sender's process handle, which can then be used to search the application's tables
for the entry to be deleted.
-105 BREAK ON DEVICE
Cause The BREAK key was pressed on a terminal or other device for which the application has
enabled break monitoring.
Format The layout of the received message described in terms of an array of words is:
sysmsg[0]
sysmsg[1]
sysmsg[2] FOR 2
Response The application should take action in one of the ways described in the Guardian
Programmer's Guide.
-106
Cause The receiving process (which must have subtype 30 to receive this message) was the subject
of a call to FILE_GETINFOBYNAME_, DEVICEINFO, or a similar function requesting device-type
information.
Format The layout of the received message described in terms of an array of words is:
sysmsg[0]
sysmsg[1] FOR 3
sysmsg[4]
sysmsg[5] FOR *
Response The subtype 30 process should REPLY with the needed information in the following form:
repmsg[0]
repmsg[1]
