I've noticed some receint problems with X im not sure how long ago it was working but it did use to work.
Its not really minicom. I suspect X and the keyboard interface. I'll try some different desktops and try commandline but somethings are fishy with kde, xorg, and minicom.
I try sending and nothing is sent. I downloaded some other terminal interfaces for serial communications like commi and cutecom. Cutecom sends info to the device(It does horible with the input though) but minicom seems not to. Out of desperation I tryed windows in a vmware machine and I still fail to send keyboard commands to the serial device. It sees stuff from it with no issues so it has to be working right?
Anyways I had to give up and use a windows machine to program the device.
If anyone has a fix I would like to know any info you can give thanks.
