a) Determining the TCP port
If DHCP sends a port number this is used.
If no value is received a default value of port 80 is used.
b) Determining IP address
Method 1:
If the IP address or DNS name is given by the DHCP server (through Axel
DHCP option) then this is the information the terminal uses to locate the
AxRM server.
Method 2:
If DHCP does not supply these values the terminal will try to resolve a
‘hardwired’ DNS name "axrmserv".
If the name is resolved the terminal can find the AxRM server. The name
axrmserv must be configured within DNS to resolve to the IP address of
the AxRM PC. A DNS alias can be used to allow the AxRM PC to have
two names, i.e. its original name AND axrmserv.
Method 3:
If "axrmserv" cannot be resolved, as a final attempt the terminal assumes
AxRM resides on the same PC as the DHCP server.
Method 4:
Only used when the location (IP address or name) and the TCP port of
the AxRM machine are specified within the AX3000 Set-Up. See Chapter
3.6.2. (This is not viable for setting up brand new terminals, as required
AxrM PC data to be already entered in the terminal setup)
The IP address of the AxRM server and the location method used is shown on
the status line:
Auto-Conf. / DHCP: aaa.bbb.ccc.ddd / AxRM (1): www.xxx.yyy.zzz:nnnn.......
The terminal sends an 'auto-configuration' request to AxRM every 5 seconds. If
no response is received after 10 attempts the terminal starts the mechanism
again, i.e. from stage 1.
