Internal non-recognised serial ports

[Ferret-Simpson]

In linux, serial ports that are not automatically detacted can be configured by the setserial command if you already know the address and irq.

 

setserial /dev/ttyS0 port 0x0220 irq 4 autoconfigure

 

Sets the /dev/ttyS0 to port address 0x220 irq 4, automatically choosing port type (16550 etc)

 

I am already aware that there is no setserial in Darwin/MacOS X, but I NEED to configure the internal port. No, an external USB adaptor is NOT an option.

 

 

Is there a way to modify the system to add a "Setserial" command, or any similar command or other way to achieve the same result? (Configuring a serial port address to an internal port number and IRQ?

 

I don't want a no.

Go to the /system/library/extensions directory and find the Apple16x50Serial.kext. Edit the plist inside to correspond to the correct port address setting and the correct vendor/id's. If it is a standard 16x50 uart serial interface the port should be activated when you load the kext or reboot.

There were two plist files inside the kext: info.plist and version.plist

 

I'll say it, I had a look through the code and neither of them seemed to deal with hardware vendor id's or ports. . .

 

There were two "Plugin" kexts inside the package aswell, I didn't have a chance to look in those, might it be possible that they do the dirty work?

 

So far I've managed to track down the VID for Wacom: 056a

Add that to the 0x220 port and IRQ and all I seem to be missing is the PID and a place to put them. PID is possibly F004 but I can't say for certain.

Any news on the subject.

Possible to add entries like, say, IOPort to the kext to get irq/port number sorted?

or you need to recompile the actual driver's binary with the right settings?

Should I even ask why you're posting in here? Yours already works!
