Modem only works at 19200

Hello All, I am using Suse 5.2. My modem is work fine but only at 19200 I set the speed to 28800 in rc.config. now I can not dial in to my ISP anymore, it dial in I can hear the handshake but than it drops the line. In the log I get "Speed 28800 is not supported" My modem is a BahnBooster 288000 (elsa) it is working at full speed under windows. How do I set up my modem to use 28800? Thanks very much Stefan -- Um aus der Liste ausgetragen zu werden, eine Mail an majordomo@suse.com schicken, mit dem Text: unsubscribe suse-linux
