I would like to make the internal modem of my laptop (toshiba satelliet 4200) work. I figured out it needs to have the LTMODEM installed.
Nut how to configure this all and how to install it and which file exactly to make it work? There seems to be dozens of version of the ltmodem in the web.

somehow the modem is detected, it is called ttyLT0, but when it comes to dial, nothing happens, the errorlog says modem gives no replay.

any ideas?
