Try running > 4 19200bps lines on modems and see if you don't drop any characters. I was running multiple high speed modems locked at 38400 under DOS and was dropping characters all the time until replacing the 16450s with 16550As and adding the 16550A driver. With the driver my 10 mhz 1 wait 286 at the time could support multiple transfers of 2510 cps at one time. -- Larry Snyder uucp: iuvax!ndcheg!ndmath!nstar!larry The Northern Star Usenet Distribution Site Notre Dame, Indiana USA
