How can I prevent client timeouts on a SQL Anywhere Database?

Resolving The Problem

QUESTION:
How can I prevent client timeouts on a SQL Anywhere Database?

ANSWER:
Description of liveness timeout (-tl) for version 5.5.05 :
A liveness packet is sent periodically across a client/server TCP/IP, or SPX
communications protocol to confirm that a connection is intact.
If the client runs for the liveness timeout period without detecting a liveness
packet, the communication is severed.
Liveness packets are sent at an interval of one quarter of the LivenessTimeout
value when the connection is idle - that is, there has been no request or
response packets sent back and forth for at least one quarter of the
LivenessTimeout value.

Description of idle timeout (-ti):
Disconnect connections that have not submitted a request for minutes. The
default is 240 [minutes] (4 hours). A client machine in the middle of a database
transaction holds locks until the transaction is ended or the connection is
terminated. The -ti option is provided to disconnect inactive connections,
freeing their locks.

The -ti option does not disconnect clients that use the shared memory
communications link.

Setting the value to zero disables checking of inactive connections, so that
no connections are disconnected.
