Hello all, I'm trying to run Automation Direct's DirectSoft 5 PLC software under WINE. Here's what I'm running: Lenovo ThinkPad T61 Laptop Linux Distro: Debian Squeeze 6.05 Wine v1.01 Direct Logic 05 #D0-05DR Serial Communication I am aware of the compatibility list for DirectSoft 5 and Automation Direct software. I am capable of running the software in virtual box but that just brings me back to the frustration of window?s. I can successfully run the software in wine if I adjust the DS500.ini COM*ENABLE= to 0?s. I have tried linking the ttyS0 to com2 (symbolically) with the COM2ENABLE=1 in the .ini and the program hangs. I've also tried Wine v1.4 and have the same issues. Link code: Code: ln -s /dev/ttyS0 /~/.wine/dosdevices/com2 I have also changed the permissions of ttyS0 to 0644 with: Code: chmod 0644 /dev/ttyS0 And the program starts, and runs but will not communicate with the PLC. I am running OP-WINEDIT Optimate configuration software just fine in wine with com2 linked to ttyS0. Can anybody throw me a bone on what else I could try? Thanks in Advance.
