[ Lots of people complaining about lost characters, lack of ProTERM interrupt support ] I've disassembled my PT.BIOS file and commented the whole thing out. Mine is configured for a Hayes 2400 and GS Modem Port. I patched it up a bit to work with my Telebit T2500 (actually, a 1 byte fix takes care of that) but it is still losing characters in emulation, and goes nuts once in a while. It seems to me that I could probably fix ProTERM up to use firmware instead of accessing the modem the way it does. It's got three main serial I/O routines: one which sends characters, one for "raw" (no scrollback, i.e. transfers) reads, and one for text reads. These routines are very short and are polled to death. I'm going to spend as much time as it takes tomorrow to make the stupid thing work with GS firmware & interrupts. I am afraid I will probably have to remove the printer routines to grab enough space to do my modifications, however. The driver is pretty tight right now. The only drawback I can think of would be that ProTERM will probably be slightly slower when using interrupts. You'll also have to have Slot 2 set to Modem Port for it to work. If anyone is interested in seeing a patched driver, leave me some mail. It should work with any HC modem on a GS port. I _hope_ it will stop the bizarre emulation problems I have at 18kbps but not at 2.4kbps. I'm using PT 2.2, by the way.
