After the OM1004 requests the user to start the Xmodem transfer, the user must select the Xmodem
protocol and the upload file (e.g., using HyperTerminal's Transfer/Send File menu option). The
OM1004 send C's for thirty seconds. This is an indication to the terminal program to use the Xmodem
CRC protocol. After thirty seconds, the OM1004 switches to sending NAK characters every ten
seconds for another 100 seconds. This is an indication to the terminal program to use Xmodem
checksum mode. Thus, a user has approximately 130 seconds to select the upload file. Usually, it
doesn't matter whether the transfer occurs in CRC or checksum mode, however, some terminal
programs don't switch automatically from CRC to checksum mode. In that case, it may be necessary
to select the upload file in the first thirty seconds, or defer selecting the upload file until the OM1004
has switched to checksum mode.
