I have been running into oportunities where the customer is looking for a smaller/cheaper device than an MC70, but they need RS232. I just entered GRIP 5178-5225 asking for an RS232 option to be included on future devices. If you have similar requirements, please add them to the GRIP to help build a case for this. http://grip.symbol.com/FindDetail.aspx?Search=1&RequestID=5225
