Hallo,

I've posted this a few day ago, but it seems it had problems to get through
the net. So I decided to post it again together with msome more problems AND
solutions.
-----------------------------------------------------------------------------
We've just obtained the TDI M2 compiler for the Commodore AMIGA. Together
with the documentation came some papers concerning known problems in
release "1.01A". This papers seem to be incomplete or at least ambigious, so
I've got some questions:

1.) There have been some postings of fixes for TDI on this list in the
    past. I've missed most of them. Could someone resend them to me
    <XBR2D96D@DDATHD21> ?

2.) The files AMIGAX.sym, CIAHardware.sym and  CustomHardware are corrupted.
    Do we need them and if yes, how can we obtain them. Simply recompile
    the DEF's will cause severe problems I suppose.

3.) This papers say that TDI is available via COMPUSERVE 75026,1331.
    If I try to access them via VAX-PSI and DATEX-P (German PSN)
    I reach a Username/Password prompt. I don't know both and I suppose
    that I'm not supposed to use the COMPUSERVE ID this way. Can someone
    tell me how to use it?

4.) TDI announced a fix diskette in it's documentation. Is this diskette
    already available ? Our local dealer hasn't got it jet.

5.) we (I) are especially interested in the RealInOut and LongInOut modules
    announced with the diskette. Are they available on the net?

6.) playing with the Amiga tools I discovered that the CreatePort and
    DeletePort routines from PortUtils had both horrible bugs. I've corrected
    both routines according to the new ROM-Kernel Manual Part 2/App. F. The
    fix is enclosed with this message.

7.) The SerialDevice.Def file misses some of the SerFlags (e.g. 7Wire). The
    SerStatus bits also didn't look like Bits for a SerialDevice (PaperOut ???)
