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.
