agrsm-20080203.tar.gz  doesnot have the recognition codes for any of
the HDA modems
Within agrsoftmodem.c ,  only the

const SUPPORTED_DEVICES agereSupDevices[] = {
  { 0x11C1, 0x0620, 0x0000, 0x0000 },
  { 0x1039, 0x7013, 0x0000, 0x0000 },

and there are no HDA audio cards in this list, which are hosts for
