XBee series 1 stop bits

I’d like to interface the PC to the HSR-8498HB Hitec servos. This servos are special for robotics, they can respond tension, current and current position. They work at 19200bps, no parity and 2 stop bits. The xbee series 1 just work with one stop bit. The series 2 can be drived with a SPACE parity that can solve the problem, but can I have the same feature for series 1 too? There is a workaround to solve this problem?
