Yup, now confirmed. It's faster to use aliases than Richard's module strcpy.
while totally ignoring the reasons why i do it that way

1, you get every opportunity to vet the data before committing to overwrite the old data
its east to vet whether by crc or any other test you can devise
2, it can receive data from multiple devices and allow you to steer the data into appropriate structures at will

if you really need speed without verification
hserin 50,mainloop,[ wait("[",21), STR MsgData \21]


you don't need any of that alias typing exercise
