Hi, thank you very much.
popen seems to works ok. But there s a problem with pclose();
when I write:
file = popen ("cu -l /dev/ttyACM0 -s 9600", "w"); //WRITE
fputs("AT\n",file);
pclose(file)
this run ok. In console:
Connected.
cu: End of file on terminal
Disconnected.
But with:
file = popen ("cu -l /dev/ttyACM0 -s 9600", "r"); //READ
there is no response when I try to close the pipe. Not Disconnected, and so i can't write one more time.
I'm trying to do this, because I need a bidirectional pipe , and the only way I know to do this is to: open to write -- > close --> open to read ---> close and another time the same
BUt pclose function failed in read mode .
thank you

yhsm-yubikey-ksm(1) General Commands Manual yhsm-yubikey-ksm(1)
NAME
yhsm-yubikey-ksm - Decrypt YubiKey OTPs using an attached YubiHSM
SYNOPSIS
yhsm-yubikey-ksm --key-handles ... [options]
DESCRIPTION
This is a small network server with a REST-like API that decodes YubiKey OTPs.
It can be used as a decryption backend (Key Storage Module) to a validation service such as the YubiCloud.
The AES keys of the YubiKeys must be present as AEAD files decryptable to the attached YubiHSM. Such AEADs can for example be created using
yhsm-import-keys(1).
Note that this daemon is single threaded - it will only handle a single request at once. A request timeout is therefor most important.
OPTIONS
-D, --device
device file name (default: /dev/ttyACM0)
-v, --verbose
enable verbose operation
--debug
enable debug printout, including all data sent to/from YubiHSM
--U, --serve-url base
base of URL for decrypt web service (default: /yhsm/validate?)
--port num
port to listen on (default: 8002)
--addr addr
address to bind to (default: 127.0.0.1)
--key-handles kh, --key-handle kh
key handles to use for decoding OTPs. Examples : "1", "0xabcd".
--aead-dir dir, -B dir
base directory for AEADs (default: /var/cache/yubikey-ksm/aeads)
--reqtimeout num
number of seconds before a request times out (default: 5)
--pid-file fn
write process id of server to this file
