I do have the [serialports] section completed. This PC actually
has 34 serial ports. Though I can get away with using just 8 with Wine.
Because I can't get ANY serial port stuff to work under Wine, I'm
wondering if somehow my setserial config is wrong - because clearly I've
had to muck about in this area a lot to get 34 COM: ports working on a PC.
Here's an extract from "setserial -ag" for COM1: and COM4:. Does this look
right ? Linux itself doesn't have any problems with the ports setup like
this. For example "minicom" is happy to chat with a dumb terminal over any
of the COM: ports.
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000
Flags: spd_normal skip_test
/dev/ttyS3, Line 3, UART: 16550, Port: 0x02e8, IRQ: 10
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000
Flags: spd_normal skip_test
Here follows a bit of log resulting from a --debugmsg +comm on a
Windows program called datapak.exe which downloads data from a weather
station data logger.

... and the program says it cannot establish connection over the serial

Now, I don't know how this Windows program is supposed to work, but I'm a
little suprised not to see any writes to the serial port at all.
Any help appreciated.
