#protocols research
4 messages in this thread
To Betty Clay 76702,337 Subject: ProtocolsResearch I have made a series of
copies of my NComm program disc. Each one has been configured for a different
protocol according to the libraries on the disc. It is my intention to go
through the practice forum and test a short upload and download on each to see
what happens. Unfortunately I will have to log out after each test as it seems
that the Compuserve environment does not allow changes to a protocol once
selected. The various options in the options menu are listed down the column
and the protocols across the top. The first list is the original settings as
received with the program. I will ignore the references to Zmodem. I do not
have a Jmodem library.
Original X Y Kermit CompB Bimodem
Bmodemplus OPTIONS XmodemCRC yes yes no no

ChopFiles yes yes yes yes yes

G&R Protocol yes no no no no

G&R HostMode no no no no no

Kermit 1k no no no yes no

For the purposes of this test series I will only operate via the phone 4153155
which accesses Compuserve at 14400baud. All discs are set to 19200baud as is
the serial configuration in my Amiga Workbench preferences. Settings in both
are 8-N-1 Library file sizes for the protocols:
XModem no file
Ymodem no file
Kermit xprkermit.library 22016
CompB xprquickb.library 12696
Bimodem xprbimodem.library 18236
BmodemPlus xprbplus 19004 Before I start
this test series, can you please advise me if there is anything I have missed
or should change/add to any of the discs. While I address my messages to you
directly as we have an ongoing communication stream and therefore know what
each other is doing, I presume that your colleagues can also access these to
provide their own input.e
Peter,
Forgive me, but I don't quite understand the reason for this research you are
doing, and I don't know of anything that could be missing.
I can tell you now, though, that for CompuServe, the best protocol to use it
BPlus. It is fast, accurate, and allows for re-starting of interrupted
downloads (as ZModem does on other systems.)
You are wise to do this in Practice forum, though.

I was wondering if the files on the Ncom disc are compatible with your system
for B,B+ and quickB as these all fail
Peter,
Have you set your serial settings for 8-N-1? If you are set for the 7-E-1
recommended for CompuServe, your binary downloads will always fail, no matter
what protocol you have. You need to set for 8-N-1, and then turn on an option
to 'strip high bit.'
I don't know anything at all about NComm except that we have a steady stream of
complaints that it does not work properly here. I've never used it, or even
loaded it into my machine – but if it has the real B protocols, they ought to
be compatible. CompuServe invented the B protocols and then distributed them
so that program writers can support them. The code is freely available and
people just have to plug it into their programs, so unless that programmer made
unauthorized changes, the protocols are compatible here.
