/dev/cuaU0 is not a composite device, is the terminal interface for one of the two serial ports on your modem (and I'm pretty sure none of them are for 'voice', but without a dmesg one can only wonder). The other serial interface (ucom1) can be accessed on /dev/cuaU1. > Is it possible to use the same /dev/cuaU* device for accessing both > ucom0, ucom1, ucom* to have voice and data functions available in the > modem simultaneously? You need to be a lot clearer in explaining what exactly are you trying to do, and what you mean by simultaneous. My 3G modem also has two serial interfaces and I can send AT commands on both of them (e.g. use one for connect/disconnect chat and the other to periodically get connection stats without fear of collisions/races). > Needed functionality seems to be integrated into FreeBSD by using 'u3g' > kernel mode driver which provides access to a modem 'ucom*' ports by > accessing to: /dev/cuaU0.1 and /dev/cuaU0.2 > How to the same functionality can be performed in OpenBSD? I don't know a thing about FreeBSD device numbering, but my guess is that /dev/cuaU0.1 and /dev/cuaU0.2 are /dev/cuaU0 and /dev/cuaU1. > Some ideas will be helpful. Read man 4 ucom, look at your dmesg carefully and please append it to your message next time. Cheers Zé --
