9.4 Asynchronous message thread
MSEsetup has a thread that runs in the background and binds a UDP socket to the
asynchronous port. The asynchronous default port is 27300 and can be changed in
the Networking screen. This thread is used to accept asynchronous messages from
the MSE 1000 modules as well as from other client applications that want to perform
functions through MSEsetup.
Modules send broadcasts specifying their network information as well as referencing
complete, foot switch triggers, warnings, and errors.
The MSEvba.xlsm file is an Excel spreadsheet that is installed with MSEsetup for
demonstrating how to send asynchronous commands to MSEsetup using Visual Basic
for Applications (VBA).

9.4.1 Asynchronous commands
Any application that can utilize sockets can interface with MSEsetup.
Command structure format:
s t r u c t A s y n c C m d S t r u c t
{
u n s i g n e d c h a r u d p C o d e ;
u n s i g n e d c h a r r e q u e s t ;
u n s i g n e d c h a r m o d u l e N u m ;
u n s i g n e d c h a r c h a n n e l N u m ;
u n s i g n e d c h a r v a l u e ;
} ;
The udpCode is always 222. This is a special command informing the Asynchronous
thread the command is not from the modules.
