Notes:  Set MESG_CNT=3 to add a 3rd message.
Set ISSUE 3=8:CMD1 to initiate MESG3 when the CMD1 element on Port 8 asserts. This
element is asserted when the “GROUPS” command is received on Port 8.
! Set MESG3A=\Rc;08:USER:0;23/ to send the message stored in the Port 8 User data
region when the ISSUE 3 message trigger condition asserts. The format of the message
is \Rc;(port number):(data region):(starting address);(number of characters)/, where the
\Rc;..../ string requests the register data from that address.
