disconnected from the USB-Cable and reconnected after 5 seconds.

1.1x and 1.2x: Regardless of how much memory is used, it is up to 40 dots in normal 
condition.

1.40: depending on how much memory is used, the erase time will vary. The maximum is 
40 dots.

In case the delete takes abnormally long, the FlashCard detects a time out and the 
message "erase memory failed - disconnect USB and try again" will be sent from the 
FlashCard.

The FlashCard should be disconnected from the USB-Cable and reconnected after 5 
seconds.

After a successful delete, the message “Please start upload data“ is displayed.
Now the data can be sent.  (To send a Lynx file into FlashCard, push “Send File“ button on 
HTerm, and select file from menu)
The end of the transmission is determined by the FlashCard via a Timeout. So, it's not 
necessary to send the configured number of KB. 
During write operations, the Status-LED will flash red.

Verify: After entering “v“ the message “Please start upload for verify“ is displayed. Now the 
data can be verified.  (To verify a Lynx file, push “Send File“ button on HTerm, and select 
the same file from menu)

When the comparision is successful, the message “Verify successful“ is displayed. 
Otherwise, if the two memory positions do not match, the message will read  “Warning – 
verify not successful.“  “Stop upload and press Anykey,“ and the comparision will be 
aborted. During comparision, the LED flashes green.

[u] write       [y] verify      [r] read        [e] erase     [m] modify byte

Write: The EEPROM doesn't need to be deleted before writing. The data is overwritten. 
When transmitting less than 128 Bytes, the leftover Bytes are overwritten with “FF“ while 
the Status-LED blinks red.

Verify: Analog to FLASH,  LED blinks green.

Read: All 128 Bytes are read and outputted. The Status-LED blinks green.

Erase: Deletes the EEPROM.

Modify Byte: This new function is available on Firmware v1.10 and above.
This option allows you to modify one byte of the EEPROM memory.
After selecting “m“ you have to send the address and the data, in Hex-Data.
To switch to Hex in HTerm, change the “Type“ (lower left side, next to the input line) to 
HEX and insert the address and data, separated by a space. 

For example: 00 30
In this case, the FlashCard will write "30" in hex to hex address "00".

Before 1.40: only 1 byte is changed every time "modify byte" is executed.

1.40: it is possible to change up to 128 bytes every time "modify byte" is executed.
The data can be sent in random order.
