Subject: [linux-dvb] [patch 2/5] mt312: Fix diseqc
Date: Sat, 12 Apr 2008 17:04:47 +0200	[thread overview]
Message-ID: <20080412150447.084696372@gentoo.org> (raw)
In-Reply-To: 20080412150444.987445669@gentoo.org

[-- Attachment #1: 02_mt312-fix-diseqc.diff --]
[-- Type: text/plain, Size: 1308 bytes --]

Correct the frequency of the emitted diseqc signal to 22kHz.
Adds sleep(100) to wait for message to be transmitted.

For now the only user of mt312 is b2c2-flexcop, and it
does overwrite all diseqc related functions with own code.
