15.8 Setting up data interfaces
Setting handshaking (flowControl)
By handshaking, two devices control data transfer between them.
A distinction is made between software handshaking and hardware
handshaking.
No data flow checking (NONE): Handshaking is not active
Hardware handshaking (RTS_CTS): Transmission stop is active
through RTS
Software handshaking (XON_XOFF): Transmission stop is active
through DC3 (XOFF)
File system for file operations (fileSystem)
In fileSystem you define the file system for the serial interface.
This machine parameter is not required if you don't need a special
file system.
EXT: Minimum file system for printers or non-HEIDENHAIN
transmission software. Corresponds to the EXT1 and EXT2
modes of earlier TNC controls.
FE1: Communication with the TNCserver PC software or an
external floppy disk unit.
