(see setting description format info here)
| Function: | Defines whether the (next) serial data block can be opened by a specific character or any character |
| Post-initialization value: | 1 (enabled) |
| First introduced: | Earlier than "baseline" V3.14/V3.51 |
When Start On Any Character is 1 (enabled) then any character received into the serial port past the end of the previous serial data block will open a new serial data block. When the Start On Any Character is 0 (disabled) then only a selected specific character defined by the Start Character Code (S1) setting (must be enabled through the Use Start Character (F1) setting ) will be able to open the new serial data block. All data between the end of the previous serial data block and this start character will be ignored.
Serial data blocks are related to routing the data in the serial-to-Ethernet direction. For more information see serial-to-Ethernet data routing .
