Question of Dual Serial
As a new owner of your Dual Serial Board, I'm very pleased and the board seems
to work well in several applications. There is one request I'd like to make.
When using the SERXI-Handler to support an auxiliary terminal, I've found that
there are some incompatibilities with respect to the Commodore AUX: handler.
The most annoying is that DEL does not delete the previous character, but
backspace does. The original AUX handler would delete the previous character
on BOTH backspace and delete. Some of the other editing control characters,
like ^U to delete part of a line are not apparently supported either, but this
is no major problem to me.
Also, it would be helpful to me to be able to access the DSR, CTS or RI
lines rapidly, as I'm using them as control inputs in a non-standard
appliaction. Would an io_Command be the appropriate way to do this?
