Serial Port Problems

[booeyOH]

Hello,
I have a modem on the Serial Port and am trying to use PHP to read/write to it. I found this:

http://www.phpclasses.org/browse/package/3679.html

It seems like it would work great, except, for some reason, on this server, when I fopen("/dev/ttyS0", "r+"), it just hangs, doesn't give an error back or anything, just hangs.

Any ideas?

Thanks.

Booey

Hi,
Can you post some more code as how are you using the class, methods etc.?

I never set a goal because u never know whats going to happen tommorow.

Even using the canned example that they have for the class (

http://www.phpclasses.org/browse/file/17927.html),

only changing the device to "/dev/ttyS0", it will hang.

If anyone has a device on "/dev/ttyS0" on a linux machine and would be willing to try out the example that comes with the serial class (in the link above) and see if they can get it to work, that would be great.

I haven't ruled out that has something to do with the way my server is configured.

Thanks,
Boeey
