throw RequestRejectedException("Unexpected string length: $length")

suspend fun Socket.readProtocolString(): String {
    withMaxPacketBuffer {
        val transformer = StringResponseTransformer()
        val copied = copyTo(transformer, this, limit = 4L)
        val length = transformer.transform()
        if (copied != 4L) {
            throw RequestRejectedException("Unexpected string length: $length")
        }
        val messageLength = length.toIntOrNull(16) ?: throw RequestRejectedException("Unexpected string length: $length")

        compatClear()
        compatLimit(messageLength)
        val read = readFully(this)
        if (read != messageLength) throw RequestRejectedException("Incomplete string received")
        return String(array(), 0, read, Const.DEFAULT_TRANSPORT_ENCODING)
    }
}

copied equals 0 when there is no device connected in the following env.
Android Debug Bridge version 1.0.41
Version 35.0.2-12147458
Running on Windows 10.0.19045

This is not a exception but it throws RequestRejectedException.

I think adam should declare -1 for copied in this situation.
