hi all:
below is my platform environment:
-------------------------------------------
ttyS1 ttyp0
-----------------------------------------
| |
| |
|(1) <---------------|
| |
serial TX
RX
Normally the ttyS1 will get the data from outside serial Rx.
but under some circumstance, I need the ttyS1 input from
1. NOT from serial Rx, but from ttyp0
or
2. both from serial Rx and ttyp0
is it possible to do that without modifing kernel tty driver by
changing parameter in /sys/class/tty/ttyS0/, etc.
appreciate your kind help in advance,
