4.2.2.12 Set station address
#include <H1Def.h>
unsigned short WENTRY_C H1SetStationAddress(unsigned char
W_POINTER address)
This function modifies the local (own) station address.
Parameters
address
Pointer to a memory location containing the modified station parame-
ters. The remaining 6 bytes contain the station address.
For an H1 environment the highest byte may not contain a broadcast-
or multicast-address.
Return value
0
H1_NO_DRIVER
H1_NO_ADAPTER
Note
The station address must be unique, otherwise it is possible that collisions occur on
the network.
The station address is independent of other protocols, e.g. IPX, if the setting
“Protokollieren = Ja” (log protocol = yes) has been specified. On some LAN’s the
MAC-driver may not be set to operate in promiscous mode. In this case you must
set “Protokollieren = Nein” (log protocol = no). Other systems refuse to cooperate
when the station address is modified at run time, i.e. the setting is “Protokollieren =
Ja” (log protocol = yes). The system is loaded drastically by the promiscous mode.
Please refer to the technical reference for your network for further information in
this regard.
Example
unsigned char address [6];
station[0] = 0x00;
station[1] = 0x20;
station[2] = 0xd5;
station[3] = 0x80;
station[4] = 0x02;
station[5] = 0x01;
H1SetStationAddress(address);
