no receive on tcp port

[fwt-dot-fr]

I receive nothing from the tcp port,
device to tcp state: unconnected
is always unconnected.

with the same configuration /etc/ser2net.conf
6000:raw:600:/dev/ttyUSB0:115200 8DATABITS NONE 1STOPBIT -XONXOFF -RTSCTS

with ser2nets:
-> showport
TCP Port 6000
enable state: raw
timeout: 600
connected to (or last connection): 600:,
device: /dev/ttyUSB0
device config: 115200 1STOPBIT 8DATABITS NONE
device controls: RTSHI DTRHI
tcp to device state: waiting input
device to tcp state: unconnected
bytes read from TCP: 10
bytes written to TCP: 0
bytes read from device: 290
bytes written to device: 10

with ser2net
-> showport
TCP Port 6000
enable state: raw
timeout: 600
connected to (or last connection): ::ffff:192.168.1.6,39162
device: /dev/ttyUSB0
device config: 115200 1STOPBIT 8DATABITS NONE
device controls: RTSHI DTRHI
tcp to device state: waiting input
device to tcp state: waiting input
bytes read from TCP: 0
bytes written to TCP: 0
bytes read from device: 0
bytes written to device: 0

Idea ?

Regards.

Same here with raspberry pi and 4.9 kernel.
Tested with other PC Linux and same result.

Same here.... weird thing is... ser2nets does receive the data.... if I connect on the monitoring port and issue a 'monitor term ' command there, I do get to see the terminal output, just not on the normally connected clients.

+1 use older version, don't remeber which exactly.

All later versions seem to be the same for my use-case... tried all seemingly relevant commits

commit 52ae6ec
--> First version that allows multiple connections, but doesn't print serial output again

commit 94bcba0
--> last version that prints serial-output to the network, but doesn't alllow multiple connections

This project is pretty much obsolete now that the original ser2net program has been updated to support multiple connections.

Thanks.... seems the upstream version does indeed do this... with the 'max-connections=X' option...
Doesn't work for the version in debian currently... but works with the git-version.
