I am looking to get a little help on the following "mov" commands, any help would be greatly appreciated:

movx A,A+DPTR
movx A,#(1+243+243)


Also if I setup a serial port buffer using 5 bytes can I just load the datapointer with the label for my buffer and then increment the data pointer to move through all 5 bytes of the buffer, as of right now I can only write to the one byte in the buffer. Anything I copy to the buffer overwrites the previous byte.....sorry for the questions but I am just learning this and am in a time crunch.

A BIG thank you to all the people that have answered my questions in the past and gave some awesome help, Thank You Very Much.
