MP 20060603 memset and memcpy arguments were backwards for Windows version. close_serial doesn't crash now.
|
||||
MP 20060618 make sure name is set up in comport_new (x->serial_device = test.serial_device) so help message works.

MP 20060618 make sure name is set up in comport_new (x->serial_device = test.serial_device) so help message works.
|
||||
MP 20060619 implemented status outlet
|
||||
MP 20060620 Add DTR and RTS control, add outputs to reflect CTS and DSR states.
|
||||
MP 20060621 Do all the above for Windows too.
