*********** *********** If you don't have a 3B2 with EPORTS hit "n" now... *********** Netlanders, This must have been asked a hundred times with respect to Trailblazers (we just got ours!) but my questions are more general. Like many 3B2 owners, we eagerly awaited the EPORTS card that support hardware flow-control but we are somewhat disappointed. For running a serial printer with DTR it is great but we're having difficulties with MNP modems, the 'Blazer, and multiplexors. I contend it is a bug that you can pick HFC *or* XON/XOFF, when in fact it would be really helpful to run both at the same time. Werer I setting up my system, I would run HFC between the system and these devices, letting the hardware and the modem talk to each other entirely transparently to everything else. Then, if I hit ^S on my terminal it will actually stop output rather than echo and disable my keyboard (I *really* hate it when that happens). Basically, hardware flow-control should be so deep in the driver that your ioctl() just sets some bits in the serial hardware and Unix is otherwise unaware of anything. This lets your MNP modem, Trailblazer, terminal or multiplexor do their own things. Then, on a higher level, the XON/XOFF can be used where needed (over a non-MNP modem, a terminal without DTR flow- control, etc.). Besides, I can't have uucp turn on HFC and turn it off when done. Sigh. Has anybody else been frustrated with this? Ideas?
