Note
For most systems, the command „arp“ can only be performed by the
user „root“.
Note
The Windows command line entry interprets entries for numeral
values with a leading '0' as octal numbers.
E.g. ping 192.168.100.015 actually goes to the host .13
Reason: octal '15' = decimal '13'
It is also advisable not to use leading zeros for ping, Arp, Telnet or
similar commands.
7.4.3 IP block formation
The INSYS Ethernet maps a serial interface on an Ethernet port. In simple words: a serial
cable (or a modem connection) is replaced by an Ethernet connection.
However, there is a significant distinction between the two transmission types: While for
the cable (or modem) the data can be transmitted into both directions as permanent
data stream, for an Ethernet connection data packets are transmitted as blocks. The IN-
SYS Ethernet therefore collects the data to be transmitted for a defined period and then
sends them to the remote terminal in one individual packet. As a countermove, the bytes
of a data packet which was received via Ethernet is continuously sent via the serial inter-
face.

The INSYS Ethernet has several algorithms which determine when the data collection is
finished and the packet is sent.

 IP block formation when the maximal block size is reached
 IP block formation when a trigger byte occurs
