Modem problem

[RAKOTONIAINA Solofoarisoa]

Hi,   I have installed the Debian GNU/Linux 2.2 potato official i386 on my computer. When using the PPP,  it couldn't view my modem which is an internal modem installed on the port COM4. Under MS-Windows98, the connection works perfectly. The type of my modem is as follows :  HSP56 Audiomodem riser from PCtel Inc. I really appreciate any help from you. Thanks in advance   RAKOTONIAINA Solofoarisoa ************************************************* Dr. RAKOTONIAINA Solofoarisoa Laboratoire de géophysique de l'environnement et de télédétection Institut et observatoire de géophysique d'Antananarivo (IOGA) Université d'Antananarivo B.P 3843 101 Antananarivo MADAGASCAR Tél/Fax : (261)(20)2225353 [EMAIL PROTECTED]
