linux - Redirect multiple UARTs in Qemu -


i emulating chip multiple uarts/usarts. want redirect uart3 /dev/uart3 on host, uart7 /dev/uart7 on host, etc. can't seem find examples or guides deal more 1 uart, , examples did find don't seem select uart dumping console/socket/whatever. (some of them use "id=id" have no idea means , qemu documentation didn't seem cover it.)

man qemu says:

-serial dev

redirect virtual serial port host character device dev. default device "vc" in graphical mode , "stdio" in non graphical mode.this option can used several times simulate up 4 serial ports.

also, add virtual usb serial ports:

-usbdevice serial:[vendorid=vendor_id][,productid=product_id]:dev

for dev substitute host's serial ports in form /dev/ttyxxx in both cases

you omit vendor , product id specification. in case qemu create generic serial usb device virto' ids
