Message-ID: <1990Nov07.155516.17815@ism.isc.com> Date: 7 Nov 90 15:55:16 GMT Sender: usenet@ism.isc.com (Usenet News) Reply-To: johnan@ism.isc.com (John Antypas) Distribution: usa Organization: Interactive Systems Corp., Santa Monica, CA Lines: 28 Interactive Systems is now the fortunate owner of many different modems. Some are Telebits, some are V.32, some are 2400 baud no-namers, etc. Unfortunately, we do UUCP with all of them. We've been looking at the transfer stats and have noticed the different flavors of modems each treat UUCP a bit different. We are looking into placing a new protocol into UUCP which copes with the higher-speed modems, but doesn't require protocol spoofing, nor does it assume your running X.25 (no f protocol). What characteristics should we shoot for when dealing with what we call, the new low-end high speed modem. This "modem" appears to have the followig basics: NOT V.32, V.42/42.bis, PEP! Totally unique protocols Can do 9600 baud without compression, but with compression can do 38.4K Either does not have a back channel, or must "turn the channel around" and can take a second or so to do it. I've been looking at a modified 'g' protocol using 2K blocks window size 7. Am I completely off track? Obviously, this works best with ASCII files in bulk like Batch SMTP. Tell us what you want, maybe we can put it in. John Antypas / Interactive Systems Corp. uucp: ...!uunet!ism!johnan Internet: johnan@ism.isc.com All statements above responsability of the author.
