From the attached serial device, send an fdc ‘[TargetUserStationName]’ command to the host
user station followed by a carriage return character
[0x0D]. This will force the target user
station to disconnect from the specified target device. In addition, the user station will send a
numeric confirmation code indicating the outcome of the command. See
Table 3.7 for
code definitions.
Confirmation codes
If you use the fcc or fdc commands, you will receive a numeric confirmation code indicating the
outcome of the command. See
Table 3.6 and Table 3.7 for confirmation codes and

Forcing a connection using SNMP
To force a connection using SNMP, the access rights that apply to SNMP control are assigned to a
user named “snmpUser.” After adding and setting access rights for the snmpUser, you can force a
switch to any of the target devices to which the snmpUser has access.
For instructions on adding an SNMP user, see the AMWorks software online help program. For
more information on forcing an external switch on the AMX switch, refer to the specific MIB file
called AMX-MIB. This MIB file is available on the AMWorks software CD. You can also
download the AMX-MIB file by visiting www.avocent.com/support and clicking
