minicom issue with file transfering using zmodem

--------------------------------------------------------------------------------

Hi all,
I am connecting a Linux machine with a Windows machine using null
modem
cable.
I am configuring the serial ports using minicom in Linux and
hyperterminal in windows.

If i am sending a file using ascii protocol from minicom i am
receiving
it correctly in Windows machine. The same is true for the windows
machine also (on sending text files from hyperterminal i am receiving
it perfectly in minicom).

But once i change the file transferring protocol to zmodem (or say x/y
modem) in both side, and starts sending a .bin file from minicom to
hyperterminal, file transfer fails with the following errors:

On start of the transfer, in hyperterminal I get "bad data packet" as
last event.
Then after some retries I get "connection time out" as last event in
hyperterminal and "got ZNAK" in the minicom window.

is this a known issue with serial transfer?
I am using minicom 2.0.00 which comes with fedora core 4.
I am running a 2.6.15.4 kernel.
