Greetings All, I recently helped someone, and will be doing it for my system, install a modem for dialin on a: 386 - 40. 8 megs. SVGA Bustek SCSI card. Serial and Parallel on some kinda card. Telebit T2500 Interactive ISC 2.2 I finally got everything working the way I wanted it. Looks good. Dials in and out and everybody is happy BUT: (There is a but) I had to resort to XON/XOFF flow control between the modem and the computer. I had set it up for CTS/RTS, but when the modem drops CTS, the computer keeps right on sending chars. So I put it back to XON/XOFF and for the most part it works fine. SO: What happened to CTS/RTS. I pretty much figured this should be working right off the git-go, but no way hose'! I had sort of a break out box that helped me to watch the control lines, so this is how I finally decided that the CTS/RTS flow control was not working. IF: Anybody has any ideas or experience with this, please drop me a line. I will need to get CTS/RTS working and I know a lot of you all out there have ISC, probably with modems. I will be glad to summarize any responses I get. Thanks in advance. Karl Nicholas karln%karln@uunet.uu.net karln!karln@uunet.uu.net uunet!karln!karln ---------------------------- Try one, try em all.

As you told nothing about the serial driver you use, I expect it's the buildin ASY-Driver from ISC. - This drivers always had problems with hardware handshake, or, simply not supporting it. Use the FAS 2.0.8 - serial driver from Uwe Doering. It should be avail- able one any of your local district machines or simply via FTP on every 'bigger' ftp-site. - FAS also supports the NS16550ASN - serial chip (which has a FIFO-buffer inside), which is highly recomended to use with a highspeed modem. - FAS works quite fine on my system (ISC 2.0.2), and also should do with 2.2 ... it surely supports full hardware handshake and is varibable configurable. Forget about the ASY :-) Greetings ...
