I don't know but the bug in Wine is obvious, in comm.c it should
check if lpstat is NULL before doing a TRACE !!!
in misc/comm.c :

BOOL WINAPI ClearCommError(INT handle,LPDWORD errors,LPCOMSTAT lpStat)
{
int fd;

fd=COMM_GetReadFd(handle);
if(0 {
return FALSE;
}

if (lpStat)
{
lpStat-
if(ioctl(fd, TIOCOUTQ, &lpStat- WARN("ioctl returned error\n");

if(ioctl(fd, TIOCINQ, &lpStat- WARN("ioctl returned error\n");
}

close(fd);

TRACE("handle %d cbInQue = %ld cbOutQue = %ld\n",
handle,
lpStat- lpStat-
replace the TRACE instruction by

if (lpStat)
{
TRACE("handle %d cbInQue = %ld cbOutQue = %ld\n",
handle,
lpStat- lpStat- }

Here is the full output from the debugger, are these functions used by many
programs ?

bye for now James.

The problem is that no one has implemented the functions SetupCom,
SetCommTimeouts, SetCommBreak or ClearCommBreak beyond simple stubs.

To help, (see documentation/bugreports) perhaps posting the last few
lines of wine -debugmsg +comm would help

Since it's a stub function, the best help would be to grab whatever
microsoft API docs you can find and implement the functions :
Or wait for the next release and see if it gets better.
