Re: Writing an "AT-Command" to a Modem

Hi HalfActivist,

thanks - that sounds plausible!

In addition to using the normal BSD APIs (open, close, read, write et al.), or their Cocoa equivalents, you'll probably need to configure the serial port (or, for "internal" modems, the pretend serial port) to the settings you need.

To do that, you'll probably want to use the POSIX terminal functions (defined in the header <termios.h>). See

for more information.

I also recall seeing that someone had written some Cocoa classes to help with serial ports; you can find them here:

Kind regards,

Alastair.
