PipeSerial

PipeSerial is a command-line utility to send some input from stdin to a serial device and return the output on stdout.

A quick example:

[tykling@container1 ~]$ echo -ne "AT\nATI" | sudo pipeserial -c 2 /dev/ttyU0.3
AT
OK
ATI
Quectel
EC25
Revision: EC25EFAR06A06M4G

OK

[tykling@container1 ~]$

Same thing with debug enabled:

[tykling@container1 ~]$ echo -ne "AT\nATI" | sudo pipeserial -c 2 -d /dev/ttyU0.3
