Configuring SQL Anywhere to read from an ASE server

I have a Sybase ASE server that I'm able to connect to with ASE iSql totally fine. The database definition in my sql.ini file looks like:

[<NAME>]
master=TCP,<servername>,<port>

to connect with iSql, I can make the following command-line call and it works:

isql -U <username> -P <password> -S <NAME>

My ultimate goal is to use SQL Anywhere's ADO.Net Entity Framework connectivity for a RIA service I'm writing. I'm trying to connect now using SQL Anywhere through Sybase Central (rather than through Visual Studio), and can't get it to work. Under the Identification tab, I use and for my credentials and leave the bottom half as "None", under the Database tab, I specify for the Server name, and under Network I check "TCP/IP", and specify as the Host, and as the Port. I get the following error:

I'm sorry in advance if I left out significant details. I'm new to Sybase, having a strictly Oracle background. If I left out anything you need to know, please post a comment and I'll update the question. Thanks for helping a Sybase newb.

There's no way to do what I was asking (though it could be possible with a proxy table, that's not a desirable solution), so I'm not going to use the .Net RIA Services framework. I'm going to be writing a standard ASP.Net web service.
