Thanks ---------------------------------------------------------------------- Date: Sun, 12 May 85 01:15:30 edt From: Micheal A. Grant <mgrant@maryland> To: telecom@bbncca.ARPA Subject: 700-555-4141 I tried it both preceded by a 0, 1, and nothing at all. It rang once, then a recorded female voice said, "You have reached the AT&T Long Distance Network, thankyou for choosing AT&T." Then silence. The message did not repeat. We do not have Equal Access yet, it's not expected for some time yet. -Mike Grant ------------------------------ Date: Sun, 12 May 85 01:26:16 edt From: Micheal A. Grant <mgrant@maryland> To: telecom@bbncca.ARPA Subject: Modem ScrewUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUps Cc: cak@purdue.ARPA This is in reply to a modem problem, which mysteryously prints a whole string of U's, then you're basically wedged. I know just what your're talking about. I've had the same damn thing happen to me using the University of Merryland's computers. I really think it's the university's Gandalf box. When it happens to me, the modem dosn't hang up, it just sits there and echos back everything you send it. Chris, do you know if you use Gandalfs at Purdue? -Mike Grant ------------------------------ Date: Sun, 12 May 85 07:54:10 pdt From: brian@SDCSVAX.ARPA (Brian Kantor) To: cak@purdue Subject: UUUUUU from modems Cc: telecom@bbncca Get whoever it is you are calling to flip the switch in HIS modem to turn off the remote diagnostics - the UUUUU you are seeing is a test pattern. Many modems would accidently drop into the test state from a burst of noise while connecting or disconnecting. On many, they first send the test pattern and then go into loopback mode, which is what it sounds like you're experiencing. Usually there is a switch on the modem card to disable this ``feature''.

I thought it was the (Vax Unix 4.2bsd) system I was talking to, but I guess it could be the modems. Both ends use Ven-Tel 300/1200 baud model MD212. Very disturbing. I've seen it maybe 6 times in 3 years.

Cantor <dgc@ucla-locus>, who recognized the unit from the description I gave, answered, and mailed me a copy of the diagram. The ringer has one coil only, with five connections. The extra three; slate, slate-red, and blue, are used only for party identification. The unit is apparently a K2254, however, this identification is NOWHERE to be found on the unit. ------- ------------------------------ End of TELECOM Digest ******************************
