next in thread | raw e-mail | index | archive | help
I am trying to setup a serial terminal. I have tested the null modem
cable and #/dev/cuaa0 sides of the serial ports with a masterpower's
serial interface and #tip cuaa0b.
On the client I am using minicom with 19200bps, 8bits, no parity, 1 stop
bit, no hardware flowcontrol, and no software flow control. I am unable
to connect to the server. I have fiddled with the flow control, parity,
bps, and terminal. I have read the handbook and faq on serial
connections. I have tried a different client and server to the same
results.
What am I missing ?
What else can I try ?
