Things like screen updates. It's not the speed of the port, though, it's the speed of the GS. If I'm at slow mode, I get about every 3rd character, but when I'm in fast mode I only miss characters every once in a while. Kinda interesting... -Greg T. I think I'm having the same problem with my //c... I'm running kermit 3.86 in vt100 emulation mode with a Microcom 9600 bps modem. The serial connection between the //c and the modem is set to 19,200bps. It seems to work fine except when a steady stream of data is sent from a remote cpu to my modem; characters begin to drop at a steady pace. Could someone please explain the ins and outs of hardware/software flowcontrol and the differences between xon/xoff and cts/rts? Kermit is certainly the most robust comm program for the //c when it comes to handling > 2400 bps communications (includes Z-LINK, Proterm) Anyone else use a //c at > 2400bps , preferably 9600bps, and want to compare notes? I'm thinking a rocket chip would help things out... Otherwise looks like I'm going to have to write my own comm program (OH NO NOT ANOTHER!!) Enough rambling.. -Paul Nakada pnakada@oracle.com nakada@husc4.binet
