I found and posted to this post How to set up an FTDI USB to serial modem adapter but am probably better starting a new one.
I have a USB Serial modem that has an FTDI chip. When I dmesg, it is recognized and shows it at /dev/ttyUSB0.
In wine, under the dosdevices, I have added a sym link (ln -s /dev/ttyUSB0 ~/.wine/dosdevices/com3) for a com port.
Everything seems to be in order but when I run the program, the com port is not listed.
I'm beginning to believe that it has nothing to do with the FTDI chip. The program claims to be looking for a virtual port. As I recall, when I ran this in Windows, I had a time getting it to recognize the port and going into the administrator computer management to assign this port to this modem.
Is it possible to make a virtual com port or is that what the symbolic link is supposed to do?
