Detailed Description

Xmodem send implementation, used for XBee firmware updates.

Todo:

Have timeout values adjust based on link latency. Start out with a high timeout (10 seconds?) and adjust down based on actual response time (maybe 150% of last ACK's delay?) Timeout for EOT should start at timeout value from last block.
