[C client] ORP version can not be set in 'sync synack' command

[fdur]

According the ORP documentation:

Sync-Acknowledge (SYNACK): Response to a sync packet, used when the recipient of the sync wishes to negotiate part of the handshake. The recipient is acknowledging the sync packet but wishes to use some value other than the default or what was sent in the original sync packet.

Response:     <packet type[1]><version[1]><sequence[2]>[,<MTU>]
packet type:  'y'
version:      ORP version supported
sequence:     unused
MTU:          'M'<mtu size>. Requested MTU size, optional (ASCII decimal, NOT null terminated)

If version is set using sync synack command:

$ ./bin/orp -d /dev/ttyUSB0 -b 460800
ORP Serial Client - "h" for help, "q" to exit
Using device: /dev/ttyUSB0, Baud: 460800, Mode HDLC
Protocol codec initialized
