I'm running FC3 on an MSI-7142 (K8MM-V motherboard), and using
the two serial ports on the m/b. I used the stock
out-of-the-shrinkwrap settings for most hardware (except for the sound
board and X drivers), and things have worked fine.
But... when connecting to a router's console at 115200 with either
RTS/CTS or XON/XOFF flow control, I'm seeing dropped characters.
Looking at a friend's router, his one's serial port connection *ONLY*
had the three-wire type of serial connection. So his couldn't possibly
use hardware handshaking (RTS/CTS). Perhaps yours can't too?
Also, check what your router says about its maximum port speeds and
handshaking protocols.
It is an 8-wire connection (over RJ-45 to DB-9), and can do 115200 (max rate)
with either XON/XOFF or RTS/CTS.
I've tried both, and they're both lossy.
The issue is on the PC as the receiver...
