OsmocomBB

I'm having troubles to get osmo-bts-trx, fake_trx and trxcon to work.

• osmocomBB 928a1a42b5aebc9afda347ed1d3112c595e6bcda (318f8b78aad5961eba6b179f84e772bff759ade3 + ChangeID I3f7c83ad0624839ce42864c70396a4397b21f514 for encode_cm1)
• libosmocore f4cd228f1e238fbc824cdbdbd5eb30d99c44e079
• osmo-bts 4650c34e9423d947bd09e06482998112b978e87f (but confirmed with earlier committs yesterday, too)

FakeTRX output looks like this:

• trxcon is not receiving responses it's looking for
• osmo-bts-trx is receiving respones for commands it never sent.

All programs run on localhost, there are no patche to change port numbers or anything like that.
