Re: RS232 Keep RTS high

So my question is can I keep RTS always high, although I have no data
to send? Or there is some way to make output buffer always full or
having some data so RTS will not get low.

Any suggestions will be appreciated.

PS. Hyperterminal works fine with the device.

You can set RTS always-high with the fRtsControl member of the DCB passed to SetCommState().
