Line Commands
92 IOLAN Device Server User’s Guide, Version 1.0
keepalive
Enables a per-connection TCP keepalive feature; after approximately 3 minutes of
network connection idle time, the connection will send a gratuitous ACK to the network
peer, either ensuring the connection stays active OR causing a dropped connection
condition to be recognised by the reverse raw service.
Applications using this feature need to be aware that there might be some considerable
delay between a network disconnection and the port being available for the next
connection attempt; this is to allow any data sent on prior connections to be transmitted
out of the serial port buffer. Application network retry logic needs to accommodate this
feature.
lock
When enabled, the user can lock his terminal with a password using the Hotkey Prefix
(default Ctrl-a) ^a l (lowercase L). The Device Server prompts the user for a password
and a confirmation.
motd
Enables/disables the message of the day on the line.
user
For DSLogin line service, makes this a line that is dedicated to the specified user. Only
this user will be able to log in on this line and they won’t need to enter their login name
- just their password.
nouser
Blanks out the User parameter, in case you want to change a dedicated user line to an
undedicated line.
