SL is a Unix (and Windows in the future?) interface for serial port devices.
API
---
start() -> Port
Load the driver, if needed, and open a port to the driver.
stop(Port) -> ok
Terminate the port, and cleanup if neccessary.
options() -> [Opts]
Return a list of the options names possible to configure:
dev - The device name i.e "/dev/ttyS0" "COM1"
baud - The baud rate (9600...115200 .. os specific)
csize - Character size (5,6,7,8)
bufsz - Receive buffer size (integer())
stopb - Number of stop bits (0,1,2)
parity - The Parity bits (0,1)
hwflow - Hardware flow control (true/false)
swflow - Software flow control (true/false)
xonchar - Flow control char when swflow
xoffchar - Flow control char when swflow
echo - Echo mode
getopts(Port, [Opt]) ->
[{Opt,Value}]
For each option Opt return the pair {Opt,Value}
setopt(P, Opt, Arg) -> ok | {error,Reason}
Set an option.
setopts(P, [{Opt,Arg}]) -> ok | {error,Reason}
open(Dev, Opts) -> {ok,P} | {error,Reason}
A combined operation of start/setopts/open.
open(P) -> ok | {error,Reason}
Open the device set by setopt(.., [{dev,Device}])
close(P) -> ok
Closes the device opened by open/1.
connect(P) -> ok.
Same as open.
disconnect(P) -> ok.
Do a hangup then close.
revert(P) -> ok.
Revert settings done by setopt.
update(P) -> ok.
Update the parameters changed with setopt.
send(P, Data) -> ok.
Transmit the iolist in Data to the device in P
