FreeTDS version and issues whiting ORACLE

I installed FreeTDS to connect to a SQL Server in RedHat 3 with Oracel 10g version 1.
I can connect and  run select statements using isql.
I created the HS Oracle connection and  started the listener. I can ping successfully the database.

When I connect to Oracle and execute  a select statement, I got the following error:
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Generic Connectivity Using ODBC]DRV_InitTdp: errors.h (2059): ;
[unixODBC][FreeTDS][SQL Server]Unable to connect to data source (SQL State:
S1000; SQL Code: 0)
ORA-02063: preceding 2 lines from ISATLK

I contacted ORACLE. They review my configuration files and they told me that my configuration is fine. Oracle advised me that the odbc driver is not compatible with 10.1 of HS Connectivity. Suggest you contact FreeTDS.

My questions are  as follows:


-          How can identify if I am using the latest and correct ODBC driver version compatible with Oracle database 10 release 1?

-          Do I missing a step?

Any ideas are appreciated.

Thanks.
