Here is what I want to do. I have my 8051 connected to the RS232 and a 256K x 8 flash memory. I want to be able to transfer a file of 256kbyte from RS232 to 8051 and then write to the flash memory continously. I am thinking of using the z-modem protocol to do the file transfer, but I am not sure how to set it up in with the 8051. If there is a better way to do this, please let me know...thanks
Do you have a particular reason for using ZModem? Zmodem is needed for sending binary files over links which may not support binary; it also has error checking & retransmission for bad lines, and supports multiple-file transfers. I wouldn't have thought that any of these were particularly necessary for sending an Intel Hex file a few feet down an RS232 cable?
Any protocol is okay....Bascially, what is the recommendation for sending 256kbytes file thru RS232???
Did you find the resule for "zmodem"?? If "yes",Could you tell me how to do. thx for your help!!
