Follow the steps below for serial transfer upgrade.
NOTE: Serial reprogramming takes several minutes at 115200 bps
baud rate (the recommended speed), but reprogramming is
possible at lower baud rates.
1. Launch a terminal session to the radio with the following
communications parameters: Baud 115200, 8 data bits, no parity,
one stop bit (8N1), XON/XOFF flow control, and VT100 emulation.
2. At the > prompt, enter program . At the ARE YOU SURE? prompt, enter
yes .
3. At the LOADER> prompt, enter erase . The response ERASED OK is
returned.
4. At the LOADER> prompt, enter program . Do not type any more char-
acters at the prompt.
5. From the terminal program, quickly select Transfer->Send Text File
and choose the correct file/file folder on the PC where the .s28 firm-
ware file is located.
This process initiates the file transfer and causes the radio to repro-
gram the inactive image. When using HyperTerminal to perform
reprogramming, no status indication is available.
6. Programming is complete when PROGRAMMED OK appears at the
prompt. The active image has now been changed to the new
package. If this message is not seen, reprogramming did not com-
plete successfully and must be attempted again.
7. Reboot the unit by typing the exit command at the LOADER> prompt.
This completes the serial upgrade procedure. To verify that the radio
is running the newly loaded firmware image, enter the srev com-
mand after rebooting.
