+ <p>The current implementation spawns a port programm
+ written in C that utilizes the actual ODBC driver. There
+ is a default timeout of 5000 msec for this port programm
+ to connect to the Erlang ODBC application. This timeout
+ can be changed by setting an application specific
+ environment variable 'port_timeout' with the number of
+ milliseconds for the ODBC application. E.g.: [{odbc,
+ [{port_timeout, 60000}]}] to set it to 60 seconds.
