I am trying to use my 8-bit as a 9600 baud terminal, but Kermit 65 drops characters at an annoying rate. Does anyone know a way (other than clearing the sceen) to keep kermit from losing characters? I would like to keep using kermit because the 80-column vt00 emulation is alot easier to use with unix machines. Thanks- -Rich rmartin@remus.rutgers.edu

Thanks- => -Rich => rmartin@remus.rutgers.edu Try turning on flow control; that should do it. It seems that the Kermit-65 screen handler is too slow (especially at scrolling) to handle even 2400 bps. I have seen proposed improvements on the scrolling algorithm which I imagine would speed things up a bit, but I doubt that it could ever handle a steady stream at 9600 bps. An increase in input buffer size would help most cases, though.

I'll bet that you could make a screen scrolling algorithm that keeps up at 9600 bps by using a custom display list, with every line of text mapped to a different location in memory. Then, to scroll the screen up a line, you merely rewrite the pointers in the display list instead of copying data. The memory holding the line which scrolled off the top of the screen is then used to hold the next line of text at the bottom of the screen. m. -- __ \/ Michael Portuesi Silicon Graphics, Inc. portuesi@sgi.com "Long before one is anything like drunk, the tongue is loosened, and words may slip out which should never have been said.

Odd, I've never seen Kermit65 drop characters at 2400 baud, Gary... That's using it with a VAX/VMS system, with all the screen-control that goes on in the EDT text editor and similar applications... And I know I never did anything about Flow Control, because it comes as a total surprise to me to hear that there's even a way to influence it. Any comments?

Michael, This isn't an Atari-related message, but I noticed you work for SGI... I work for a company which sells turnkey Digital Image Recorder systems, based on the DEC MicroVAX computer. Some of the systems we've placed in the field are configured to connect, via Ethernet, to SGI-based turnkey graphics workstations, and we've had some incompatibility problems. Evi- dence suggests it may be a TCP/IP "tuning" problem, either on the VAX or on the SGI box; I have software tools for manipulating the VAX side but there appears to be NOTHING on the SGI system(s) for examining or tweaking Ethernet interface parameters. I don't presume that you, yourself, necessarily know ANYTHING about this -- but I wonder if you could recommend anyone I could talk to about it? I've found it impossible to approach SGI on the "authority" of my customer's SGI service contract, because THAT expired before SGI had even gotten my customer's system up-and-running, and my customer is loath to pay by the hour for out-of-contract assistance. I am hoping that as a "fellow vendor" I might bypass this bottleneck. Any suggestions? Thanks in advance for anything you can suggest.

It tends to lose stuff when scrolling. Cursor movement and such aren't really as much a problem.
