Ah, concerning automatic flow-control handling of the serial device: A couple of months ago I had to write some software for an HP310 in HPBASIC. Well I really couldn't stand the HPBASIC environment for development, so I developed the source on our Sun fileserver. I wrote a script which prepared the source so the HP could read it as ascii program source. I use Dnet, so I would 'put' the completed files on my ram disk, shut down dnet, flip my rs232 switch & cat the files to the HP (wrote a file acceptor basic prog.). Well, interesting thing, the Amiga refused to perform flow control - neither Xon/Xoff or RTS/CTS if I remember correctly. No amount of coaxing with preferences would change it's mind. Rebooted; Worked. Turned out that any time after starting up the initial Dnet connect window, I permanently lost handshake capabilities until I rebooted. I didn't even have to start up the Dnet protocol. Looked at Dnet source - as if I thought I'd know what to do about it, mailed Matt the info, I he had no idea why either. I dont' know if Matt ever figured out what was going on, but I don't have an easy way to test with Dnet 2.xx anymore anyway. Basically, why couldn't Preferences changes reset the handshake mode? ======================================================= Kent Polk - Southwest Research Institute kent@swrinde.nde.swri.edu ------------------------------------------------------- "If we do not change our direction we are likely to end up where we are headed." =======================================================
