thanks for you cooperation on this, I haven't heard anything from the

I've attached result.tar.gz because the size of this mail would be too

if I inline the results or just attach them.
There you find the resulting-log-files.
the names of the files are self-explaning

Thanks a lot for your help and have a nice weekend

What I'm looking for are clues indicating *why* the Brother receivers are not happy with the TCF signal.

Nov 19 07:42:59.90: [21652]: HylaFAX (tm) Version 4.1.8

Didn't you upgrade to 4.2.0 ? Or was that just your laptop? In any case, there *could* be complications in 4.1.8 that were fixed in 4.2.0 that I cannot remember.

Anyway, here's the TCF signal as received by your successful attempt to your HylaFAX receiver. The TCF signal is supposed to be 1.5 seconds of real zero-data. At 14400 baud that would be 2700 bytes.

Nov 19 07:43:12.69: [21652]: RECV: TCF 3052 bytes, 2% non-zero, 2699 zero-run
Nov 19 07:43:12.70: [21652]: --> <5:49 45 52 0D 0A>
Nov 19 07:43:12.70: [21652]: --> [10:NO CARRIER]

First off, you'll notice that before the zero-data begins that the sending modem transmitted a bunch of 1s (0xFF). This is normal and is a way to "fingerprint" a Class 1 sender. Class 1 requires that the modem continuously transmit 1s until the DTE starts sending data to it after raising a transmission carrier. As far as I am aware, there is no way to prevent those 1s from occurring, and as far as I have ever tested they are harmless. However, your modem seems to put more 1s there than other modems that I have. Notice this on the sending-side:

  Nov 19 07:43:09.50: [23109]: <-- [11:AT+FTM=145\r]
  Nov 19 07:43:10.93: [23109]: --> [7:CONNECT]

Meaning it takes 1.43 seconds for it to "raise the high-speed transmission carrier". However, if you examine T.31, you'll discover that the modem is not supposed to wait until the carrier is raised before it responds with CONNECT. It is supposed to respond with CONNECT *as*soon*as* the command is acknowledged and when the carrier is begun to be raised. This is done to minimize the number of 1s that need to be injected by the modem before any data is received from the DTE.

As for the 1s at the *end* of the TCF signal, those are unnecessary and not required by the Class 1 specification, and are a result of how your Devolo modem works. However, to have a bunch of 1s at the end of the TCF signal is not uncommon.

In the end, you have a string of 2699 bytes of zero data with a lot of 1s preceding it and following it.

I am not certain why the Brother fax machines are not happy with the TCF signal. It is possible that they do not like the 1s at the end or the beginning. My guess is that there just are *too many* 1s. Unfortunately, this is something that the manufacturer will have to resolve. Hopefully they can, and hopefully it does resolve the problem.
