Using Technician Interface Software

File Handling
The following information applies to configuration files you transfer between a
remote workstation and a Bay Networks router:
The YMODEM protocol truncates binary files
received
in a batch transfer
operation. The YMODEM header specifies the truncated size.
YMODEM sets the file modification timestamp field in the header of all
transmitted
binary files. Note, however, that the timestamp is subject to a
specific time-zone reference.
Error Checking
YMODEM performs the following error checks on file transfers between remote
workstations and Bay Networks routers:
If YMODEM detects 10 or more errors during the transmission or reception
of any one packet, it cancels the transfer in progress.
If an unexpected error occurs before a file is completely received, YMODEM
deletes the incomplete file.
Canceling a File Transfer
While waiting for the beginning of a file transfer, YMODEM treats two CAN
(control-x) characters received within 3 seconds of each other as a request to
cancel the operation. CAN characters do not cancel the operation if received while
a transfer is in progress, unless you specify the
n option flag in the Technician
Interface
xmodem command line.
Modem Interface Differences
If you are not using a Hayes compatible modem locally attached to your
workstation, you may need to follow interface line control procedures appropriate
for that modem. Such procedures may be necessary if, for example, quitting the
terminal interface program (for example,
tip or Wfterm) fails to switch the modem
to an on-hook state. Going on-hook should cause the dialed connection between
the local and the remote modems to be dropped.
You may also encounter differences in modem interface cabling requirements.
