Just tried dumping a text file to my 703 at 1200 baud and you're right, after about 500 characters or so, it can't keep up with the input. Is there any way to put a delay after characters / line on Simh? I tested again by dumping the same text file via TeraTerm using a 15ms delay per character and 350ms per line and it seemed to work fine.
Don't the RS232 control leads take care of this?
They should but I don't believe they are present of the RPi board
They sort of exist on GPIO #30 and #31, but their use is not standard, and your typical level shifter only does TX/RX. I just went through this on a recent project with a RPi connected to an (actual) VT100 -- Couldn't go faster than 4800 baud and expect it to work at all, and even there users typing on the terminal could cause spurious escape characters to be generated. I am thinking of redoing mine with a standard USB-to-serial dongle... wouldn't get the Pi kernel console there, but I could still have a getty. Incidentally the RF environment within the VT100 itself is more than the Pi's 3.3v single-ended external I/O can handle. ;) -- Jameel Akari
