It works great at 300, 1200 & 2400 baud, but I can't get it to work at higher speeds (the main reason for the exercise is to allow high speed downloading). Here is the setup: Apple II GS, Rom 01 1.25 Meg (Apple memory expansion card) Modem speed set in the control panel to 19200 (before cold restart) Proterm V2.1 If I match the 'on-line' speed in Proterm to the NeXT setting at 300, 1200, or 2400 everything works as expected. If I mismatch the speeds I get garbage (as expected). If I set Proterm's speed to 4800, 9600 or 19200 & leave the NeXT at 2400, I get effective communication at 2400 (i.e., the Apple's speed can't seem to go above 2400). If the NeXT is set to a matching speed above 2400 I get garbage. Is anyone successfully using Proterm V2.1 with a straight (on-line) connection at speeds greater than 2400? jim burns -- James E.
