wiz550 packing condition length


I would like some information about the packing
condition (char delimiter) between 2 serial/ Ethernet network module.

Could you confirm, that the wiz120 module have only
one byte (in HEX) for packing condition while the wiz550 module have 4
bytes ?


yes. in case wiz120, have only 1 byte.
but in cases wiz550s2e, wiz550sr, have 4 bytes.
