Hi all,
There is such a thing like " stty -F /"your serialdevice" -a" to view your serial setting
for example:

[root@localhost root]# stty -F /dev/ttyS0 -a
speed 9600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;

echoctl echoke
[root@localhost root]#


I would like to ask, how can i find the "configuer" of the serial port so that i don't need to modify the setting everytimes i reboot my computer?
e.g stty -F /dev/ttyS0 57600 ( how to save that setting)

I think it wud be easy to configure for u if u use minicom...
give minicom -s in command line

Hi curious_srk,
I know using minicom is sometimes much convenient that the /dev/ttyS0
But i don't know how to send test file over minicom on 2 linux machine to check where there are loss over the serial cable. would you give me some hints on how to transfer file over minicom? as what i need to do in /dev/ttyS0 is using "cat" command.

Thanks
