We have come across a problem with the serial bootloader and / or|
Hyperterminal that I hope some of you might have experienced before.
Our board incorporates a 56807 and we use the Motorola serial
bootloader to load flash (S-records) together with Hyperterminal to
transmit to the target. Our lab PC (old Pentium Pro, 150MHz) and the
laptop I use in-the-field (500MHz Celeron) both use Win98. I have
never experienced a problem sending s-record text files with these
machines. However, I recently tried to update the 807 flash with
Hyperterminal running on a Dell Pentium IV (> 2GHz) running XP and we
cannot transfer the s-record text files to the bootloader! Likewise
on an 800MHz Dell desktop running Win2000. We get the bootloader
message, start the ASCII send and that's it... it just sits and sits
and does nothing. No error messages either. After checking
Hyperterminal setup parameters for the 10th time, we have come to the
conclusion that there must be some issue with either the
Hyperterminal version on the later machines (different Win OS
versions) or timing issues connected to PC speed performance. This
is all standard stuff, so I was really blind-sided by this problem.
Has anyone else run into this one?
Hyperterminal <-> serial bootloader problem
Back in November of 2001 we have found similar problem to what you are experiencing. Here is portion of message from one of our engineer:
“…Windows 2000 hyperterminal "free" version shipped by microsoft has a bug that causes file downloading to take approximately 10 times as long. Only customers running windows 2000 will experience this problem. It does not exist on windows 95 or NT. The fix is included in Hyperterminal PE (Professional Edition) version 6.3 but costs $29.95 for business use. It is free for personal use.”
My guess WinXP has the same problem. Try professional version of hyperterminal and see if it helps.

HyperTerm is not the only serial terminal emulator that exists. I'd search
around for a
free one before I spend any money on an M$ perpetual-beta piece of software.
Use TeraTerm Pro, it's free, 100% reliable and has a lot more features
Last time I downloaded it from
ftp://riksun.riken.go.jp/pub/pc/misc/terminal/teraterm/ but if link is dead I
can upload it to the files section.
