[net.micro.att] 7300 uucp woes -- "IN SEND/SLAVE MODE

daveb@rtech.UUCP (Dave Brower) (07/25/85)

Running the stock uucp on an at&t 7300 with one phone line, talking
to rtech, a 750 running mt xinu 4.2, I am getting the following LOGFILE
errors receiving mail:

  rtech!daemon (7/24-22:14:30) (C,144,15) IN SEND/SLAVE MODE (INPUT FAILURE)

The phone is disconnected, and the 7300's daemon uux's all the mail that
got delivered OK.  The bad news is the that phone on the 7300 is gets
scrambled:

* A data call from the telephone manager will dial and connect, but
	disconnects as soon as you type anything.
* Trying to switch the line to voice fails; no dial tone is at the phone.

The 7300 has to get rebooted to straighten things out.

TWO QUESTIONS:

- What causes the SEND/SLAVE foulup, and how can it be avoided?
- How can the 7300's phone system be reset w/o rebooting?

THIRD QUESTION:

- Anybody gotten c-kermit running yet?

Thanks in advance.  I will summarize mailed responses solely to
net.micro.att.

I too have been plagued with SEND/SLAVE MODE foul ups.  Usually dartvax
(a 785) hangs up and aborts the send from my 7300.  I do not have the
problem with my phone being irreperably hung up.  uucp calls dartvax
back about an hour later, they make up, and transfer the files without
further foul up on the second try.  This recovery is automatic and
dartvax is a local call, so this has been tolorable.  Still I thought
it strange.
