Hi, Dave,

Cyclades Corporation has developed and released a new product, called
Cyclades-PC400, which is a digital Remote Access Server. This board
interacts with T1/E1 lines, and is capable of making and receiving
analog or digital calls, through internal DSPs, which work as modems.

Each T1/E1 channel used to host a call is being controlled by a char
device (/dev/ttyCMnn). The driver for the Cyclades-PC400 was written to
make the card work in the Linux Kernel. I am attaching the driver patch
gzipped, with a request to apply it in the 2.5 kernel. The patch was
generated from the kernel version 2.5.17.

Thanks,

Helio Fujimoto.
