Causes the printer to calculate the CRC for the currently selected sector and transmits the
result. This is performed normally after downloading a sector to verify that the
downloaded firmware is correct. The printer also calculates the CRC for each sector
during power up and halts the program if any sector is erroneous.
The printer transmits ACK if the calculated CRC is correct for the selected sector; NAK if
the CRC is incorrect or if no sector is selected.
Example:
MSComm1.Output = Chr$(&H1D) & Chr$(&H06)
