Stream Mode (S mode)
In stream mode, InterSystems IRIS does not attempt to preserve TCP message boundaries in the data stream. On sending, if the data does not fit in the message buffer, InterSystems IRIS flushes the buffer before placing the data in it.
On receiving, data up to the maximum string length can be received. All reads wait for the full timeout for terminators to be reached or for the buffer to become full. When this mode is disabled (the default), you are in packet mode.
Jobbed processes that inherit TCP devices are automatically set to Stream format. You can reset the format with the USE command.
