LinuxQuestions.org - wine and serial port app

distro: ZW 4.6.1
kernel: 2.6.22.1

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:

Code:

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)

Code:

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 

crwxrwx-w- 1 root tty 4, 64 2007-10-05 10:04 /dev/tts/0

root[drive_c]# setserial -abGv /dev/ttyS0

/dev/ttyS0 uart 16550A port 0x03f8 irq 4 baud_base 115200 spd_vhi skip_test low_latency

here are the relevant kernel modules:

Code:

root[drive_c]# lsmod | grep ser

serial_cs              21252  0 

8250                  23828  4 serial_cs,8250_pnp

serial_core            20032  1 8250

pcmcia                37548  2 serial_cs,parport_cs

and interrupts:

Code:

root[drive_c]# cat /proc/interrupts

          CPU0      CPU1      

  0:    1855508          0  IO-APIC-edge      timer

  1:      7494          0  IO-APIC-edge      i8042

  3:          0          0  IO-APIC-edge      parport0

  4:      1321          0  IO-APIC-edge      serial

<snip>

ports:

Code:

root[drive_c]# cat /proc/ioports | grep -2 3f8

<snip>

03f6-03f6 : 0000:00:1f.2

  03f6-03f6 : libata

03f8-03ff : serial

04d0-04d1 : pnp 00:02

0910-091f : pnp 00:08

<snip>

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!
