Registers DS:DX must point to the current full pathname, and ES:DI
to the new pathname. Once that's been arranged, the program moves
5600h into the AX register and calls INT21h. If there is any
trouble, the carry flag is set and the number is put in the AL
register. If there is no trouble, 0 is put into the AL register.
The final call to INT 21h, function 4Ch ends the program with the
ERRORLEVEL set to the whatever was in AL.

MOV AL,41h
MOV DX,3F8h

The above code outputs a byte of data (the value 41h loaded into
AL in the fifth line) to serial port COM1. It first checks the
status of the COM port 3FDh (the port address of COM1's Line
Status Register), then enters a loop, alternately rereading the
status and checking bit 5 of the return value with the instruction
TEST AL,20h. When the bit comes back set, indicating the serial
port is ready to transmit data, the routine outputs the data by
OUTing it to port address 3F8h, where the serial port's Transmit
Holding register is located.
