MOXA TTY Device Naming Convention
If the
Smartio
C168 Series is successfully configured, there will be two tty devices
created for each port at
/dev
directory: one is
non-MODEM tty
(e.g. ttye11), and
the other is
MODEM tty
(e.g. ttyE11). The two devices are actually accessing the
same physical port except that the MODEM tty has to check the ON status of DCD
signal to be able to open device, and closing device automatically as DCD signal is
OFF.
The convention of the MOXA tty device name is
/dev/tty{e-f}{1}{1-8}
, where:
"tty" + "A" + "B" + "C"
Port ordinal number, 1-8
Always 1
Board ordinal number
"e" or "E": 1st MOXA board
"f" or "F": 2nd MOXA board
Capitals indicate a MODEM port
Standard tty device prefix
For example:
T
x
R
x
/dev/ttye11
/dev/ttye12
/dev/ttye13
/dev/ttye14
/dev/ttye15
/dev/ttye16
/dev/ttye17
/dev/ttye18
