- Driver for the following Lan Media family of serial boards:
-
- - LMC 1000 board allows you to connect synchronous serial devices
- (for example base-band modems, or any other device with the X.21,
- V.24, V.35 or V.36 interface) to your Linux box.
-
- - LMC 1200 with on board DSU board allows you to connect your Linux
- box directly to a T1 or E1 circuit.
-
- - LMC 5200 board provides a HSSI interface capable of running up to
- 52 Mbits per second.
-
- - LMC 5245 board connects directly to a T3 circuit saving the
- additional external hardware.
-
- To change setting such as clock source you will need lmcctl.
- It is available at <ftp://ftp.lanmedia.com/> (broken link).
-
- To compile this driver as a module, choose M here: the
- module will be called lmc.
