sending hex codes through com port 1

[rowantrimmer]

I have a string of hex codes BE 2A 3F 00 00 1B that I need to send through com1 set to 19200 baud and 1 stop bit.

Is this possible in PHP ?

Not directly through PHP...if you're using windows you could find a COM object to interface with, or write a quicky console app in your language of choice that takes data from the command line and spits it to the com port.

yes, you can communicate with serial devices in php. you need to be on unix and have php compiled with the switch --enable-dio
once that requirement is fulfilled, you can use the direct IO functions.
http://php.net/manual/en/ref.dio.php

dio_tcsetattr can be used to set parity, baud rate, stop bits, etc.
and
dio_write can send your hex data.
