-connect mode name [flag] hostport timeout
-connect READ name [flag] storevarb [maxchars timeout]
-connect WRITE name [flag] data [nchars]
-connect QUERY name querystr [flag] replydata [timeout maxchars]
-connect CLOSE name
-connect POLL name
-connect NOPOLL name

MODE:

• SOCKET - network port (default mode)
• SERVER - network connection for fScan image server/client
• CLIENT - network connection for fScan image server/client
• DBAX - network connection to DBAX database server
• COM - serial port

FLAG:

• Opening
  • 1 - open for reading
    
  • 2 - open for writing
    
  • 4 - listening port; wait for client to connect
• Writing
  • 0 - default
  • 1,2 - write data variable DATA

• Reading
• 1 - expect single return value
• 2 - expect table (list) to br read

Note: fScan server connects with flag=7; fScan client with flag=3.

If you attempt to WRITE or QUERY a connection, that has not yet been opened, CONNECT will look for the HOSTPORT specification in a user variable called “connect_CNXNNAME” (where CNXNNAME is the name of the connection). If found, CONNECT will attempt an auto-connection to that network location before attempting the WRITE/QUERY. This is equivalent to inserting the command:

   -connect name $connect_name

For example, if you routinely connect to a DBAX database server, you could define 'connect_dbax' in your CONFIG file as:

  <uservarb name="connect_dbax">sagan.dhe.duke.edu:5570</uservarb>

Then you could communicate with that server by simply using commands like:

   -connect dbax query "select subjid,exam,sex,age from exams" 2 examtable
