This is an interpose layer for asyn octet drivers. It adds the feature to wait after every single character written to the device until the device echos it back. Some very crappy devices need this.
In the startup script, after loading the asynInterposeEcho
driver and
setting up an asyn octet port,
call asynInterposeEcho
to add this interpose layer to an existing
asyn octet port/address.
asynInterposeEcho port, address
require asynInterposeEcho
drvAsynSerialPortConfigure "device", "/dev/ttyS0"
asynInterposeEcho "device"
