Hi Nephish, Are you using pyserial or rolling your own? Normally you can write and read to the /dev/ttySXX file at the same time; since they're special files, not ordinary files, the driver handles that.
Handling both writing and reading in your program's flow control is a wholly different matter, though. You might need to use select() to avoid blocking. Are you using two completely different scripts for reding and writing? There is some valuable info, if not about python, in the Serial Programming howto, at: http://www.tldp.org/HOWTO/Serial-Programming-HOWTO/ Hugo nephish wrote: > Hey there, > i am developing on a linux computer with the serial module.
