vgetty does not switch to data (but mgetty does!)

I had the same problem with several Rockwell based modems (mainly Supras). 
The problem was the trailing "#CLS=2".  The modem is taking this as "Dont
autodetect, just answer the call as a class 2 fax".  I fixed it by
changing the code near the top of answer.c from:

     if (modem_type == Mt_class2)
          {
          bit_order = 0;
          fax_mode = "2";    <<<<<<<<<
          };

to 

     if (modem_type == Mt_class2)
          {
          bit_order = 0;
          fax_mode = "0";    <<<<<<<<<<<
          };

This is ok because the "AT+FAA=1" takes care of telling the modem
that IF the call is a fax then use class 2.  The only problem with this fix
is that you'll probably have trouble if you try to set vgetty to "fax only"
mode but I havn't had any need for that.
