Virtual Serial Interrupt..??

Hi, i am using PIC16F877.
I need to receive serial data from 2 devices.
I assigned two different streams for both devices, one is using the
hardware serial of the controller (TX = C6, RX = C7), while the other
virtual serial (TX = C4, RX = C5).
Both serial work fine but I need to put both of them in interrupt mode.
Is it possible using INT_RDA ?

The #int_rda only works with the hardware UART, which is on pins C6 and C7.

You can use the #int_ext for the hardware UART, but must you put the Rx on pin B0 in your #use rs232() statement. Pin C5 has no interrupt
capability.
