Greetings all,
A (hopefully) quick question:
How do I get a serial port to not echo bytes?
Background: iPAQ target, recent CVS version of eCos, gcc 3.0.3,
Insight 5.1. We can receive just great using non-blocking reads, but
the driver is echoing the bytes back before we 'see' them; we need to
control what gets echoed back.
I looked at the Ref Manual, walked through parts of the code; I did
find a no-echo flag in tty mode but not in raw ( e.g. cyg_io_read() )
mode. There seems to be no config key (e.g. cyg_io_set_config() which
has the right parms to read or set...
Am I missing something obvious? What's the best way around this?
Regards,
David
