distro: ZW 4.6.1
I am running wine 0.9.46 with an application Dynamic-C ( a compiler for the rabbit line of embedded processors).
The program loads data to code space on the development board via a serial connection. I have linked: dosdevices/com1 -> /dev/ttyS0 and set up the system.reg entries.
the data seems to be getting sent out:
root[drive_c]# cat /proc/tty/driver/serial
serinfo:1.0 driver revision:
0: uart:16550A port:000003F8 irq:4 tx:7032 rx:6
but the information is not getting back to the program in 'wine space' ? I have tried running strace -o ~/dc.log wine <appname> and made some progress by renaming mixed case files to upper or lower case based on file not found errors.
here is the rest of what I've looked at, if anything else is of help please ask.
serial port info: (I have tried tweaking /dev/ttyS0 with the low_latency flag and numerous baud rates)
root[drive_c]# dmesg | grep tty
00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
root[drive_c]# ls -l /dev/ttyS0
lrwxrwxrwx 1 root root 5 2007-10-05 08:39 /dev/ttyS0 -> tts/0
root[drive_c]# ls -l /dev/tts/0

here are the relevant kernel modules:
root[drive_c]# lsmod | grep ser

So I'm wondering if there is something in wine or a service that needs to be enabled to receive serial communication properly?
thanks for looking!
