Serial port handshake lines... (DTR)
We are having some trouble porting a program from PC-Linux to the Etrax
developer board. The problem is that in the PC, whenever we open the serial
port the PC raises both the RTS (pin 7) and the DTR (pin 4) lines. But the
same code in the ETRAX machine only raises the RTS, leaving DTR low.
We have not found in the documentatio any reference to the DTR/DSR
Thanks a lot.
