AWAN 3886 Servers
•
NonStop Telserv, used by applications such as TACL and the Pathway Terminal
Control Processes (PATHTCP2). Using the 3886 AWAN 3886 servers, the
TELNET session is initiated by the server port.
•
FASTPTCP Spooler Print Process (T8932); using the 3886 AWAN 3886 servers,
the session is initiated by the FASTPTCP print process.
The asynchronous ports on 3886 AWAN 3886 servers have these common
characteristics:
•
RS-232 EIA electrical signaling
•
Common asynchronous signaling speeds up to 115.2 kbps; 7 or 8 bit, even, odd or
no parity
•
Support for dialing into the ports using Point-to-Point (PPP), Serial Line Internet
Protocol (SLIP), and CSLIP protocols
•
Support for the following dial-in security protocols:
°
Remote Authentication Dial-In User Service (RADIUS) security
°
Challenge Access Protocol (CHAP)
•
Basic TELNET access for dumb terminals where the session is initiated by the
terminal.
•
Support for FASTPTCP protocol, including HP Tandem Transparent Protocol
(TTAP) printers.
•
Support for other asynchronous printers through TELNET and Line Printer
Daemon and support for asynchronous terminals and emulators.
The 6530 protocol support is available on HP 3886 servers by installing the optional
AWAN 3886-6530 Flash RAM card. This support includes these port AWAN types:
•
T6530 for 6530 family of terminals and emulators
•
FASTP for improved operation with non-TTAP serial printers
•
ATAP for non-standard asychronous devices. (ATAP is only available with third-
party GAP software.)
Current loop for AWAN 3886 (16 and 32) models is supported by using an external
16-port RS232 to Current Loop 20-milliampere converter (3886-CL). The RS-232 to
Current Loop converter is a 16-port external hardware converter that converts the
AWAN 3886 RS-232 interface to current loop on a line-by-line basis. Because only
RJ45 connectors are supported, only AWAN 3886-16 and AWAN 3886-32 models can
Note. The origination of outgoing connections using these protocols is not supported.
