If the card is a network card, it will immediately acquire the new network parameters and
disconnect all telnet sessions to that card. If a terminal card is in the slot, or if the slot is empty,
the network parameter update is refused, but the network parameters for that slot will be saved
to control card memory.

When the

NETWORK command is used with a card slot letter as a command qualifier, it will

attempt to change the parameters only for that card slot. In all other aspects, the command
behaves the same as if the

/ALL qualifier was used.


If a bootp server is present on the same network as the SCS3230 network card and bootp is
enabled on the network card, then the network card will use the IP address and subnet mask
assigned by the bootp server rather than those assigned by the sys admin.

Once a network card has been assigned an IP address either by a bootp server or by the sys
admin, then the ConsoleServer may be accessed by telnet. Connecting to the default telnet
port reaches the user login; connecting to port 5000 reaches the sys admin login.

Modem Command


The

MODEM command allows manipulation of the modem card initialization string. When the

command is entered, the sys admin is prompted for the new initialization string. Typing a new
initialization string and pressing

<ENTER> will create a new initialization string for the modem,

while just pressing

<ENTER> will accept the current value. After pressing <ENTER>, the sys

admin is asked to confirm the changes to send the string to the modem. Typing

YES and

<ENTER> will send the initialization string immediately to the modem card, while typing NO and
<ENTER> discards the entered initialization string and keeps the old string. If the modem card is
not currently installed, the settings are not sent, but are kept in control card memory. The
control card will send those settings in memory when a modem card is installed.


sys admin>>MODEM
Enter accepts present value
Init string | > ATB2H0
Save changes and update modem card? Yes or No: No>yes
Modem card not installed in slot A, init string saved

Sys admin>MODEM /DEFAULT
Current modem init string is: ATB2H0
Set modem to factory default value of: ATH0S0=1
(write out YES) Yes or No: No>yes
Modem card not installed in slot A, init string saved

sys admin>>


The sys admin may also reset the initialization string to the default value by entering the
command with the default qualifier in the form

MODEM /DEFAULT. When using the /DEFAULT

qualifier, the current initialization string is displayed, along with the factory default string. The
sys admin is asked to confirm the use of the default modem string; typing

YES and <ENTER> will

send the default initialization string immediately to the modem card, while typing

NO and

<ENTER> keeps the old modem string.
