COMPAQ CONFIDENTIAL - NEED TO KNOW REQUIRED
■ If the modem is not configured correctly in the operating system, the
operating system may fail to communicate with the modem and
periodically retry this operation. These periodic attempts will gain
ownership of the modem from IRC making it unavailable for login.
Check for proper operation of the modem by temporarily disabling IRC.
When proper operation with the operating system has been verified, re-
enable IRC.
Cannot obtain a login prompt in shared
mode
When dialing into the managed server, the phone is answered and the modems
complete negotiation, but a login prompt does not appear on the management
console after three carriage returns are entered.
Explanation: Three carriage returns are used to positively identify that an
incoming call is intended for IRC. If this sequence is not correctly received by
IRC or if IRC did not own the modem at the time the call was received, you do
not receive a login prompt.
Solution: Assuming that the login prompt can reliably be obtained when the
modem is in dedicated mode, the following are possible solutions:
■ Insure that you are sending three carriage returns (Enter key) within 10
seconds after a connection had been established with IRC. If any other
character is received, or the carriage returns are received after the
timeout period, the call is incorrectly forwarded to the operating system.
■ The modems on the managed server and the management console may
be incompatible – even if the modems seem to work properly in
dedicated mode. If the modems do not establish a consistently clean
connection, spurious and/or erroneous characters received after the data
carrier detect (DCD) signal interfere with the carriage return sequence,
incorrectly forwarding the incoming call to the operating system. This is
a problem particularly if the modems are from different manufacturers
or of different speed classes. Try using the same type and brand of
modem in both the managed server and the management console.
