[Ovmsdev] Shell syntax to write a value

Hi, I can easily read a PID value using the shell syntax in the web browser : "obdii can1 request device 7e4 7ec 22ddd00" for example. I understand that "0x22" is used to read data by identifier, and I read that "0x2E" would be used to write data by identifier but what would be the correct syntax to write a value to a PID in the shell ? or it is not possible yet ?
