Re: 115,200 serial port speed problem. Oh, that's too bad. :-( Technically, every new PC has the correct serial chip to do that speed with no problem. The symptom of it not working correctly would be jumbled or missing characters on the screen not a modem to modem disconnect problem. But it looks like your experience puts a lie to that notion. One other thing to check before giving up is to make sure the PC and modem use "hardware handshaking" not "xon/xoff software handshaking" for flow control. Try one more time to make sure it wasn't just a bad line that time. Short of that, I guess you'll have to choose stability over speed. Further background info (not related to your stability problem): The v.44bis compression protocol is on by default on most modems and it has a best case compression ratio of 4 to 1 (regular text). If the data is already compressed such as a zip file then no further compression is attempted. But with downloading text such as an SI web page the improvement is conspicuous. With the old 28.8 bps modems the 115,200 speed was ideal. With the newer modems now connecting in the 40s and low 50s, the 115,200 serial port speed is now less than ideal as far as the 4 to 1 ratio goes but is better than nothing and is pretty much the conventional limit using the built-in serial ports and an external modem. An alternative to get more than 115K is to buy an extra high-speed serial card or use an internal modem that connects right to the bus so you can use the 230,400 speed when setting up your modem which maintains the correct 4 to 1 ratio with the 56K modem. Good Luck! Jimmy Liberato
