The devil is in the details of port and driver configuration. Windows provides a rococo collection of capabilities for a basic RS-232 UART. If it thinks it the port might really be a modem, or if the port itself has a dedicated "provider", then things can get even more complex quite quickly. For a real fun read, track down the documentation on establishing a data call under the Windows Telephony API and try to make sense of it. Hand coding a send/expect module to dial the phone with classic Hayes AT commands (even after handling all the phone-line errors like no answer, wrong number, a FAX answered instead of a data modem, etc.) looks quite pleasant after that...That's curious -- I've never had such an issue before so long as I built the DCB correctly and called SetCommState(). But you may know something I don't.In any case, good luck :) My recommendation is just to keep in mind that you may want to port this later, so when you're coding things, keep in the back of your head "How might I be able to easily port this later?" when you write a function, etc.-- Matthew P. Del Buono
For a ported serial module, see: http://lua-users.org/lists/lua-l/2007-09/msg00465.html Stefan's link seems to be down, has anyone have a more recent URL?If needed, one can get the code from me (I haven't used it in few years, though). Would be pleasant for someone to make it a Rock.
