I need to be able to send a 'data block' from a PC to a device that's attached to the PC through COM1 and a RS232 connection. This will trigger the device to begin sending data to the PC. The data block that needs to be sent to the device is:
G
where is a data linkage escape character (hex 10h) where is a block start (hex 02h) where G is the code that gets the info going where is a block end (hex 03h) where is a 2 byte CCITT CRC-16 code
The device will then send data to the PC in a similar manner.
This is WAAAAAAAYYYYYY above my head. Can anyone help me out?
