About Linux drivers for COSA/SRP synchronous serial boards
Linux drivers for COSA/SRP synchronous serial boards- The COSA and SRP are synchronous serial boards. This means they can be used to connect any synchronous serial device (such as a high-speed base-band modem) to your PC with Linux. Base-band modems are usually used over leased lines and can have throughput from 64kbps to several megabits per second.
