Sharp PC-E500 to PC link issues

[fy789]

The LOAD command will automatically open the port when it is invoked;
this is documented in the PC-E500 operation manual.

I bought the RS232C-to-USB cable from tmfg.jp
to facilitate file transfer from PC to Sharp PC-E500.

I follow the instruction on their website to transfer
a file from PC to the E500:

1. First, I connect the cable to the PC and the E500
(Drivers on the PC side are preloaded)

2. Then I set up the E500 port by using
OPEN "9600,N,8,1,A,L,&H1A,N,S":CLOSE

Is the CLOSE really necessary?

Have you tried it without the CLOSE?
