A4 Software reset of the LAN-Modem
Socket 8888 has been implemented in case the LAN-Modem
ever needs to be completely reset. If a connection is opened on
this port, the LAN-Modem immediately closes it again and then
performs a software reset.
Use of the system password
If a system password has been configured (see section
Extended configuration of the LAN-Modem), this must be null-
terminated (=[password] + 0x00) and sent to the LAN-Modem
2s after a connection has been successfully opened. If the LAN-
Modem does not receive a correct or even any password within
this time, it sends the message PASSWD? followed by a null byte
(0x00) to the client and closes the TCP connection.
If no system password is configured, then as the example
shows the LAN-Modem immediately closes the TCP connection
as soon as it has been established and performs a port reset.

Following this reset all the buffer contents are deleted
and any still active connections are closed - the LAN-Mo-
dem is in its base state! This reset can be performed from any
station and should be done only in extreme cases!
