Dial in on Acceleport Xe

I have an Acceleport Xe 8-port card.
It is working under RedHat 6.2
It has a Login on dumb terminal on PC, but when a modem is connected (USR Sportster) SD and TD leds are flashing without a connection. In inittab ttyD000-ttyD007 is -t60 38400 vt100, which is working for ttyS0,ttyS1 and some chase cards.
I am lost in conf files. HELP!!!

Try the “cu” test and confirm modem configuration covered in the following URL:
