[Wine]Serial Communication

[Jochen Roedenbeck]

I try to use SimoComU, a tool to control frequency converters, on Wine.
Since version 2004-07-16 it opens its main window, and most functions
seem to work. Anyway, it does not communicate over the serial line. I
see the following output:

trace:file:CreateFileW L"COM1" GENERIC_READ GENERIC_WRITE OPEN_EXISTING
attributes 0x0
trace:file:RtlDosPathNameToNtPathName_U (L"COM1",0x4066eed4,(nil),(nil))

As I understand that log, the program tries to set the speed to
38400 bit/s and to configure the line to even parity (among others).
But, if I run "stty -a -F /dev/ttyn00" (to which com1 is a link to),
then I see no change. The parameters are not set. So I set them
using stty to get further.

The program apparently tries to write to the line, then, as the
output is:

trace:file:WriteFile 0x9c 0x4132b160 24 0x415640d4 (nil)
trace:comm:ClearCommError handle 0x9c cbInQue = 0 cbOutQue = 0
trace:comm:PurgeComm handle 0x9c, flags f
trace:file:WriteFile 0x9c 0x4132b160 24 0x415640d4 (nil)
trace:comm:ClearCommError handle 0x9c cbInQue = 0 cbOutQue = 0
trace:comm:PurgeComm handle 0x9c, flags f
[etc.]

But nothing happens on the line. On the other hand, if I enter the
command "echo xxxxx >/dev/ttyn00", the bytes are transmitted.

I have no idea where to look now. Could anyone help me?
