When I try to install a extrenal modem(28.8 bitsurfer) and use wvdialconf, I get an error" Port Scan<*1>: Ignoring ttyS0 because /dev/mouse is a link to it." Now Im using a ps/2 mouse and it looks like my potato box is reserving com1 for the mouse. How can I remove that link and will it be safe to remove it?
