Resetting FBUS port

Hi,

I'm using a PIC to talk to a Nokia 6150 on the FBUS line and I'm having a slight problem. Every once in a while, the phone and the PIC's commuinications will break down for some reason and I'm not exactly sure why.

Turning the PIC off and on makes it better in that it seems to reset the COM port and everything works fine again then.

What I would like is a way to reset the communications in software or hardware so that the COM port won't hang and I won't have to turn the PIC off and on again.

Thanks

Ken
