How to send Hex 0x1A via PHP - GoFuckYourself.com

mkx · 12-15-2009, 12:55 AM

I am trying to communicate with a modem connected to my com port via a PHP script. I got everything working except for the last command which is supposed to send 0x1A to the modem. I tried a few variations including:

Code:

ser_write(hexdec("0x1A"));
ser_write("\r\n");

but it just types out 26. It is supposed to represent control-Z and in my terminal program (terminal by Br@y) I trigger it with a macro that says "$1A".

Hope someone can help.

Try:

ser_write(chr(26));

If I said I loved you with there a 97% possibility of you being a guy, would that make me gay?

Thanks so much
