Multiple RTserver Connections

Usually, as shown in the code for A Hello World! Program, you use TipcSvc.getSrv to create a single global RTserver connection. In some cases, you may need to create multiple RTserver connections from your RTclient:

To create multiple RTserver connections, use the TipcSvc.createSrv method. This creates new RTserver connections independent of the global RTserver connection created by TipcSvc.getSrv. TipcSvc.createSrv allows properties to be associated with a TipcSrv object so that each RTserver connection can have its own option settings.
