RTS/CTS Lines

All communication must use RTS/CTS handshaking as described in the Simple Serial Interface Programmer’s Guide, p/n 72E-40451-xx. If bypassing hardware handshaking, the host must send the WAKEUP command before all other communication or the first byte of a message can be lost during the scanner wakeup sequence. Zebra recommends not bypassing RTS/CTS hardware handshaking.
