I just installed SuSE 7.3 linux including the supplied wine distro. I'm trying to run a single board computer from Zworld called the Rabbit. The specific app name is dcrab619.exe. The gui comes up with no problem but when it tries to talk to the serial port I get these messages from wine: err:string:CompareStringA (s1=(null),s2=""...): Invalide NULL string err:tooltips:TOOLTIPS_WindowProc unknown msg c017 wp=00000000 lp=40fc0b3c fixme:comm:SetupComm insize 400 outsize 4096 unimplemented stub Every time I try to connect to the Rabbit the "fixme" line above repeats. Does anyone have a clew or better yet a patch for this problem Thanks for anyones help, Andrew
