Hi， Peter and all developers
Yes， I need to describe it clearly.
1、I want make the qemu serial support crtscts
2、Problem: the machine's guest is windows, the machine's host is centos. The qemu emulation pci-serial.
A printer （model is BTP-2001cp）use the serial to print. The machine connect the printer by serial port.
The data printed by the printer is missing some data.You can see picture 1 is lost some data, picture 2 is normal.
