Z-modem Serial Data Transfer Progress Bar Issue

Hi,

I'm currently using Windterm 2.6 Prerelease 5 and encountered an issue while attempting to transfer approximately 30MB of data via the serial interface. I configured the baudrate to 2Mbits/s.

When I enter lrz in the console of the serial interface, a window pops up allowing me to choose the file for transfer, which is convenient. However, upon selecting the file (~30MB) for transfer using z-modem, I noticed some unexpected behavior with the progress bar at the bottom:

1. The progress bar quickly reaches 99%
2. The transfer rate displays as approximately 25MB/s (unlikely)
3. The bytes transfered within a second is almost same as 30MB

As a result, I'm unable to accurately monitor the status of my transfer. Despite these issues, the transfer ultimately completes successfully.

Could you please advise if this is a known issue or possibly a bug that needs to be addressed?

Thank you for your assistance.

Reproduce a roughly 30MB z-modem transfer through the serial interface at 2Mbit/s, using lrz, and observe the progress bar and transfer-rate values. Trace the progress calculation from the transfer UI or serial-transfer entry point; done means the displayed percentage, byte count, and rate track the transfer accurately while it completes successfully.
