because the TCP ports are different). However this does create ‘phantom’
sessions, as the initial sessions are still active from the server’s perspective,
and must be killed by the server.
This can be done with the ‘keepalive’ process, manually killing or rebooting.
In some situations it may be beneficial to have always the same TCP port for an
AX3000 resource (to avoid phantom sessions or to identify connections). This is
the fixed port assignment. With this method the AX3000 resources are always:
session 1 = 1024, session 2 = 1025, ..., session 8 = 1031, aux1 port = 1032,
aux2 port = 1033 and parallel port 1034.
Note: changing this method takes effect at the next AX3000 boot time.
A.10.4 - The 'Nagle's Algorithm' Parameter
This parameter is for AX3000 models 55/55E, 65/65E and 75/75E.
The Nagle's Algorithm controls behaviour of the output network dataflow of a
TCP/IP device. This algorithm allows the number of datagrams sent by the
AX3000 to decrease. However a certain latency may be noticeable due to the
caching of data before transmission.
This algorithm is disabled to prioritise performance. However some operating
systems require this function to be enabled.
Note: enabling/disabling this operating mode takes effect for the next TCP/IP
connection (no need to power off the AX3000).
A.10.5 - The 'Telnet Break Code'
This parameter is for AX3000 models 55/55E, 65/65E and 75/75E.
For the telnet session, the <Ctrl><Alt><Pause> hotkey sends a 'break' code to
the host. This break code is defined by the RFC 854, this is 'IAC BREAK'.
If needed, this break code value can be modified. The extra values are:
- AO (Abort Output),
- IP (Interrupt process),
- none (<Ctrl><Alt><Pause> generates no code).
Note: a new break code value takes immediately effect.
