A standard Mac serial port, when connected to the Personal >Laserwriter LS, transfers data to the printer at approx 970 Kbit/s. >So, the Amiga's serial port is a 1.2Mbit device? > Output from the Amiga can go as high as 1 megabaud, but input is seriously limited to 19200 on an Amiga 500 with some fast ram, and I have heard the Amiga 3000 does pretty good inputting 38400 on the built in serial device. I have not yet played with high speeds on my A3000's built in serial port, but a friend with an A2500 has told me 38400 was no problem. There is a software limitation to catch data comming in, but outgoing data will go as fast as you set it. They really need to add a few buffers to the UART in the PAULA chip, if they want to make some of us happy...But then, who knew in 1984 we would all be using V.42bis modems that wants to run at 38400? I mean, 2400 was fast THEN! Oh yeah, my Commodore A2232 multi-serial card came with a readme file saying its valid baud rates were 110, 300, 600, 1200, 2400, 4800, 9600, 19200, 115200 I gotta get my friend over here with his Mac IIcx, and hook up the old NULL modem cable and see what speeds we get between the Mac IIcx and the A3000. I forget what the top speed was that the Mac could take in...I'll take notes next time... Ron -- C-UseNet V0.42d Ronald Kushner Life in Hell BBS +1 (313) 939-6666 P.O.
