I am looking for a solution to allow me to run IP over a number of sets of existing 115KB RF links which have RS232 async ports.

I am keen to purchase the RB133 units however have suspicions as to whether the console port will reliably support PPP.

Can anyone confirm whether the port is usable for PPP with either RouterOS or OpenWRT.

Yes you can use Serial-port for PPP, try disable the system-console.

Thanks for the assistance.

We now have 4 on the way, due tomorrow.

Mikrotic tech Support got back to me pronto with the following:

Yes you can use serial port for ppp connections.
Disable console:
/system console disable 0 ;

now you can set up ppp client or server over com port.

/interface ppp-client add null-modem=yes port=serial0 disabled=no ;
the same for server

Have anyone been able to make a ppp link over rs-232 and a null modem cable?

By Default Serial Port on Routerboard configured for console, if you want to make the serial port to become normal serial port for dialing modem you can turn off the console service: " /system console disable serial0 " and then you can configure the ppp dial-out (Client) or dial-in (SERVER).
