Is it at all reasonable or worthwhile to even *think* I could write an alternate driver like usbradio but that uses some kind of 'generic' audio driver that outputs and captures audio from just about any 'common' PCI or ISA type sound card via it's normal linux driver.. and route radio PTT to something like a pin on a serial or parallel port?? I've been doing this for quite sometime with the Linux soundcard packet radio drivers where it almost doesn't matter what sound card you have installed it works.. Was just wondering if this is possible.. and if it may be a worthwhile project for me to eventually take on.. And what the good and bad may be in doing so. Is all the work that has been done on the cm108 driver so specific to the cm108 that it could not be easily applied to another sound device? Or is this rather simple and I should get to work on it? Thanks for entertaining my curiosity... I also thought that might be a really good learning project for me to do and learn how to do it... also why or why it may not be a good idea. Thanks!
