cyclades-serial-client 0.92ubuntu3 (arm64 binary) in ubuntu xenial

 This is the client for network serial port emulation via the RFC 2217
 protocol as used by Cyclades terminal servers and other products. It
 consists of a daemon that manages a pseudo-tty and a shared object to take
 over the tcsetattr() and tcsendbreak() library calls to redirect their
 functionality over the network.
