Sprint 598 USB modem..

It works…

Things to know:
“Com rate” for the primary com channel to the virtual usb/comm port must be forced to 9600.

The default route created by the ppp-client will not properly “tear down” on a router reboot.
To correct the default route issue:

  1. Create a small script to:
    A) Wait 15 Sec (to give the system time to init the ports)
    B) Disable the ppp-cleint virtual interface.
    C) Wait 2 Sec. for the interface to shutdown and the route to be removed.
    C) Re-Enable the ppp-client virtual interface. (this re-creates a valid default route)
  2. Create a schedual entry that runs the “bounce script” at startup.

WORKS GREAT LASTS LONG TIME !!

I have not had the chance to see if the microSD slot works with RouterOS yet, but I dont see why it would not..

I will give it a try and post results…

If the script is needed post a request and I will post it…
