Strange Device name in Infocenter of KDE

[Hamid <mylists@spils.com>]

Hi

I am trying to make my winmodem alive under Debian. I have done the 
necessary steps and loaded the lt_modem and lt_serial modules.
And when the system boots up, I get the message:
"ttyLT00 at 0xfc00 ( irq = 10 ) is a Lucent Modem"
But I can not find such a directory/device in /dev folder.
But to my surprise, when I check the info center of KDE3.1, I can see a 
character device named "62 tts/LT%d"
Can anyone help me ?
Thanks
Hamid
