Details

1) Begin a Ymodem download to a embedded system.

2) Wait for the the remote system to send 3-4 0x43('C') characters(it is requesting the download to start) before starting a Ymodem send.

3) Based on the number of 0x43's that TeraTerm has received, it will send a initial file size packet to the remote device that is the incorrect size. This bad packet(more than 133 bytes long) is a correct packet that is duplicated by the amount of 0x43's received. If seven 0x43's were received before the file transfer was started, then the initial packet will have six correct packets lumped into a single bad initial file size packet.
