Subject: TAC buffer expansion news

BBN recently updated the Arpa/Milnet TAC software to version #113.  As
I mentioned in a previous message, I am now able to upload files using
the 128-byte record "XMODEM Protocol" via any TAC that I have tried.
The input buffers were previously 64 bytes.

Today I tried using the 1k packet size option available in some newer
versions of micro and mainframe implementations of the various
versions of XMODEM.  It worked perfectly at 1200 bps through three
different TACs that I tried!

It would seem safe to assume that BBN has expanded the input buffers
on many, if not all, ports to over 1024 bytes.

If you have had problems in the past uploading to your host via a TAC,
try again.  Your TAC announces in the sign-on banner what version of
the software it is running.  If it says #113, you're in business!
