Couldn't read IEC1107/IEC62056 meter through USB

In most of the case, people couldn't read 1107 meter through USB  to serial converter because ,there will be baud rate negotiation in between the communication and at that time IR LED will not get enough power in between the communication.
This problem arising because most of optical reading unit uses RTS some other pin for powering IR.But when baud rate changes ,this pin also get affected in case of USB-Serial converter.
