Yes there are some other errors there.

See the following simple example adapted from your code, it complies
fine with vala 0.5.6.

(I should use some short namespace but I haven't just because I'm little
lazy ;) )

using GLib;

public class Multiplexer : Object
{
        Context ctx;

        public static int at_command_cb (Context ctx, string command)
        {
                Multiplexer m = (Multiplexer) ctx.user_data;
                debug( "CB: atCommand %s", (string)command );
                return 1;
        }

        public Multiplexer( bool advanced, int framesize, string device, int
portspeed )
        {
                debug( "Multiplexer created for mode %s, framesize %d, device %s %d",
advanced? "advanced":"basic", framesize, device, portspeed );
                ctx = new Context();
                ctx.at_command = at_command_cb;
        }
}

====================== Vapi file ====================
public class Context
{
        public void* user_data;
        public AtCommandCallback at_command;
}

[CCode (instance_pos = 0)]
public static delegate int AtCommandCallback (Context ctx, string cmd);
