Modem Operation
All three commands have the same effect: An attempt is
made to set up a call to the LAN-Modem having IP address
172.16.232.73 to TCP port 8000.
1
If the preset TCP port number 8000 for the LAN-Mo
dem is not usable in special network environments,
this value can be changed using the Telnet configuration.
Additional information can be found in the section
Expanded Configuration of the LAN-Modem .
• S=0|1|2|3
The LAN-Modem has a non-volatile memory for up to four
destination IP addresses. By specifying a value between 0
and 3, the IP addresses stored here is used for the call set-
up. If only
S is entered without a numerical value, the
addresses stored in position 0 is used. The command &Zn
is used to write to the non-volatile address memory.
•
L
When using L instead of the IP address, the dial-up is
repeated using the last used values. If no address has been
dialed since the last reset of the LAN-Modem, the message
ERROR is returned.
•
; (Semicolon)
Entering a semicolon to terminate the dial-up command
causes the LAN-Modem not to automatically return to data
mode after a successful call set-up, but rather to remain in
command mode.
Replies for the dial-up command
• CONNECT
The network connection with the desired destination system
was successfully made, and the serial application connected
therre accepted the call. If the dial-up command was not
terminated with a semicolon, the LAN-Modem is now in data
mode, i.e. all entries are sent transparently to the
communication partner
