The same behavior with the recommended putty and Tera Term. When you start typing after a break of approx 10 seconds, the first character is not there.
Is it a bug or a feature?

it has been a known issue which I think is fixed with latest firmware - at least I haven't seen this behaviour on my systems for a while (but mostly connected via ssh anyways)

The Intel® Edison board has a known error on all UARTs. When the Intel® Edison board goes into low power sleep, the UART internal FIFO and interface is powered down. Therefore, a two-wire UART (Rx/Tx) will lose the first received character whenever the Intel® Edison board is in sleep mode. In order to avoid this condition, when sleep mode is enabled, a four-wire UART (Rx, Tx, CTS, and RTS) is required.

Can confirm. The version that came installed in the Edison had that problem. After I updated the image, it is now working fine as of Edison v120. (configure_edison --version).
