In a program I am working on I am having trouble getting the RAM serial driver to open the printer port properly. When the program starts it does a RAMsdopen on the modem port and sets the speeds...etc. This works fine. When the user asks the program to switch to the printer port I do a RAMsdclose on the modem port, then a RAMsdopen on the printer port. Both of those calls return without error, BUT when I try and do anything to the printer port like set speeds I get a "device not open" error. Switching back to the modem port again works fine, using the same close/open process. Anybody have any ideas why the printer port isn't working right? Before you suggest it...I have appletalk turned OFF and there is NO imagwriter or other printer driver on the disk. The only thing I can think of is that the port has to be opened by the device manager open before RAMsdopen will work...does that make any sense to anyone? Greg Corson ...seismo!iuvax!kangaro!milo
