Tera Term 4.96 (XMODEM-1k updater for the XPA125B)
Recommended version Verified — manufacturer file

The open-source Tera Term terminal program, version 4.96 (portable zip), used to send .xgf firmware to the XPA125B by XMODEM-1k. Owners on the Xiegu-XPA125B group report 4.96 works where newer versions stall at the end of the upload; Xiegu's former download page offered 4.96 as its update tool.
Read before installing. Third-party open-source software (Tera Term Project, BSD-style licence), not a Xiegu product. Release year from the archive's file dates (2017-08-31). Radioddity's V2.0.1 package bundles Tera Term 5.3 instead. Xiegu's own "Update-Tool TeraTerm.rar" could not be recovered.

Tera Term 4.96 (XMODEM-1k updater for the Xiegu XPA125B)
=======================================================
WHAT THIS IS
------------
Tera Term 4.96, the free, open-source Windows terminal program (Tera Term
Project), as the portable zip archive from the project's GitHub release
page. Its files are dated 2017-08-31.
The Xiegu XPA125B has no dedicated updater: firmware (.xgf) is sent to
the amplifier's bootloader by XMODEM with 1k blocks from a terminal
program, and Xiegu's own instructions are written for Tera Term. This
particular version is kept because:
- a Xiegu-XPA125B group post (groups.io #102) names "TeraTerm v4.96
(this version only ..newer ones apparently don't work)" and says
Xiegu's download page offered it as "Update-Tool TeraTerm.rar";
- owners reported newer versions stalling at the end of the upload and
4.96 (SVN 6938) working (#134), and a failed update cured by using
4.96 with the 1k option (#245).
Radioddity's V2.0.1 package bundles Tera Term 5.3 instead, and
Radioddity's guide says any terminal program with XMODEM-1k will do.
Xiegu's "Update-Tool TeraTerm.rar" itself could not be recovered.
APPLIES TO
----------
Windows PCs updating Xiegu XPA125B firmware (and, per Xiegu's tutorials,
other Xiegu radios updated by XMODEM such as the G90). Tera Term itself
is a general terminal program; the release notes do not list supported
Windows versions for 4.96.
BEFORE STARTING
---------------
- The XPA125B firmware (.xgf) to be loaded, and its entry's README.
- The data cable's COM port visible in Device Manager.

INSTALLATION
------------
Nothing is installed: unzip and run teraterm-4.96\ttermpro.exe. The
archive's README-archive.txt notes that teraterm.ini may need editing
for the interface language. Then, for the XPA125B (Radioddity's
instructions and M0PQA's write-up):
1. In the New connection dialog choose Serial and the cable's port.
2. Setup > Serial port: 115200 baud (M0PQA).
3. Put the amplifier in its bootloader ([PA] + [BAND] + [POWER], then
[PA] = UPDATE) and wait for "Waiting Connect.C".
4. File > Transfer > XMODEM > Send, choose the .xgf file and tick 1k.
VERIFYING
---------
Help > About Tera Term shows the version. For the amplifier, see the
firmware entry's VERIFYING section.
IF SOMETHING GOES WRONG
-----------------------
- Before running, compare the archive's SHA-256 with the value above,
which is that of the GitHub release file retrieved on 2026-09-18.
- Transfer fails with "Cannot not find an application" on the amplifier:
the 1k box was not ticked (see the firmware READMEs).
