| |
I'm working on moving an application off of NT to Linux that reads a 64kbps mpeg audio data stream off the 25 pin port of a Sealevel 4021 (shunted for v.35), parses the data, and writes it to disk.
Ideally, I'd like to keep using the same hardware that the old system uses.
Unfortunatly, as best I can tell, the sealevel driver focuses on HDLC and the use of the sealevel as a network device.
Four (cascading) questions:
Is there any current mechanisms in the driver for doing raw capture from the device?
If not, how foolish an undertaking would it be for an experienced, but kernel driver green, C programmer to do the right thing and hack together a sealevel serial-ish driver that would allow for device special file IO to the card ports?
If extremely foolish, does anyone know of a v.35 device that, on linux, has the ability to do raw capture?
If none, how about an rs422 device that does so? (I can get an adaptor for v.35 to rs422).
