SCS PXFastUpdater 1.00.06
===========================

Portable firmware updater for SCS modems.
Supported modem families: DR-9400 and DR-7X00 only. Older modems, including
the PTC-II series, must be updated with the legacy SCS update software.

System requirements
-------------------
- Windows 10 or Windows 11, 64 bit
- SCS modem connected through VCOM or Ethernet/Telnet
- No installation or additional runtime is required

Quick start
-----------
1. Start PXFastUpdater-1.00.06.exe.
2. Select a COM port or a discovered network modem.
3. Click "Connect modem" and wait for the green CONNECTED indication.
4. Select the firmware file.
5. Click "Start update" and do not disconnect the modem or power supply.
6. Wait for the green SUCCESS / Checksum OK on Modem indication.

The updater first tries the fast UPDFAST protocol. If the installed modem
firmware does not support it, the updater can use the slower legacy UPDATE
protocol instead on a supported DR-9400/DR-7X00 modem. This does not mean
that PTC-II or other older modem models are supported.

After connecting, "Read modem log..." saves the modem system log. Current
firmware transfers log data in 65536-byte blocks; older firmware is supported
through the existing 256-byte protocol.

Security note
-------------
This beta executable is not yet digitally signed. Windows Defender SmartScreen
may therefore report an unrecognized application. Run the application only
when it came from the official SCS download link and its SHA-256 checksum
matches SHA256.txt.
