I'm trying to follow this guide Connect your Mac to the internet using a dial-up modem but I can't find the option to add a modem on my Mac.
Maybe I'm looking in the wrong place? Where should I find the modem option?
Thanks a lot.
MacBook Air
Yes the modem is connected externally. I can open a terminal and type AT commands on /dev/tty.usbserial-1422410
However I need to set up ppp to transmit and receive data through the modem.
The documentation says there should be an option in interfaces called Modem but I can't find it.
Thanks a lot.
It's a modem with an RS232 serial port. It's connected to the MacBook via a USB <-> RS232 converter and is recognised as a serial port. That's how modems have worked since 1962.
RS232 can be used for many things and MacOS should not automatically assume that any RS232 device connected to it is a modem. So it shouldn't recognize the device as such.
However according to the Apple documentation I should be able to add a Modem in the network configuration and then choose the serial port it's using. Except the option to add a Modem is missing on my MacBook.
I can't find anything about this being an optional add-on package to install but it should, according to Apple's documentation, be included in Catalina and also Big Sur (I can't upgrade yet because I need to use software that isn't compatible with Big Sur). The only other thing I could think of is that Apple silently removed support for serial modems and forgot to update the documentation.
Just because it is a modem doesn't mean the OS can identify it as such. It's a piece of hardware that provides some identification to the OS. If the OS doesn't know what it is (either because it is not in its list of valid devices or because they dropped support for modems altogether), it won't display it.
The documentation says there should be an option in interfaces called Modem but I can't find it.
Contact the manufacturer. Perhaps the modem needs you to install software to make it usable.
Your Mac doesn't have a modem to use. You would need some sort of USB dongle to connect to a phone line.
It's a serial modem and the drivers for the serial connection are included in MacOS.
What I need is to configure the ppp client in MacOS... this is device independent.
Thanks a lot.
It doesn't appear your MacBook Air recognizes the device as a Network Service modem. Does the manufacturer claim it should work on a MacBook Air running Catalina?
modem option missing
