We talk to one site that can't handle anything faster than 9600 baud. We talk to another site that talks 19.2 to its modem. Ideally, we'd like to autobaud between the TB and the Sun, so that we'd always be talking at whatever baud rate was expected. Unfortunately, if you set the S51 register to 254 or 255, and you want to talk 19.2 kbaud, you have to type AAT initially instead of AT. Our uucico doesn't (seem to) let you change how it talks to the modem, so I can't just tell it to use AAT instead of AT. What I've done instead is to set S51 to 5, and always talk 19.2 to the modem. If I don't have flow control, is this a good idea for the 9600 baud site? Will the uucp spoofing suffice for flow control? It seems to be working so far, but there are occasional delays (2+ seconds) when transferring large files. Even better, can somebody tell me how to get CTS/RTS flow control on the Sun? Thanks for any help. Brian H. Powell National Instruments Corp. brian@natinst.uucp 12109 Technology Blvd. cs.utexas.edu!natinst!brian Austin, Texas 78727-6204 AppleLink:D0351 (512) 250-9119 x832
