Hello
I have now tried with a projection Design f1 projector and I still cannot get comport to talk to the projector
I can open the port, I see the device, it accepts settings but when I send the ascii it still has no effect.
The f1 command is
:POWR1'CR'
[58 80 79 87 49 13[
Is there some simple way to test this?
It's got to be me doing something wrong
In the cmd terminal I can type> mode com4:19200, N, 8, 1
And I get the status for the device:
Status for device COM4:
-----------------------
Baud: 192
Parity: Non
Data Bits: 8
Stop Bits: 1
Timeout: ON
XON/XOFF: OFF
CTS handshaking: OFF
DSR handshaking: OFF
DSR sensitivity: OFF
DTR circuit: ON
RTS circuit: ON

Yeah, <CR> is most likely carraige return, which is 13 in ASCII:

So you need to send something like (ASCII values):
[13 42 112 111 119 61 111 110 35 13(
