RE: downloading my code onto 68hc11 - Mark Schultz - Jan 22 11:02:00 2005

Regarding the use of BUFFALO to program EEPROM -

In Hyperterminal, after setting up the COM port, baud rate, etc., go to
File/Properties, select the Setup tab, then the "ASCII Setup" button.
You should see a field that lets you specify the "Line delay". Try
using a value of 160 mS to start out with. You may find that you need
to use a larger value here for reliable EEPROM programming, as it is
dependent on the size of the S-records you are sending; you need to
specify 10 mS for each byte in the data field of the longest-length
S-record in your object file.

I would also suggest that you go to a site such as TUCOWS and look for
a alternative freeware/shareware terminal. Hyperterminal can be
somewhat clumsy to work with. I don't know if BUFFALO issues some sort
of prompt or start character after it processes each line when loading
a S-record file, but if it does, you could use a terminal (with a
appropriately configurable ASCII transfer module) to have it pace its
line-by-line transmissions based on whatever prompt char is issued -
assuming there is one. It has been a while since I've used BUFFALO so
I don't remember all of its conventions.
