Setting-Up the Office Server in Interactive Mode

18 AXEL Office Server

2.4 - SETTING UP THE SERIAL PORTS

The [Serial] menu allows an administrator:

- to set line parameters (data transfer rate, handshake, etc.) for the serial

ports,

- to associate a network service with each serial port (telnet, lpd, etc.).

2.4.1 - Line Parameters

To modify the line parameters of port X, select [Serial Lines]→[Line X]→[Line

Parameters]. The first parameter is:

Line Type: three values are available:

- direct: for a direct connection

- dedicated: for a dedicated (or leased) line

- telecom: for a voice modem or an ISDN adaptor.

Note about modem control

The 'dedicated' and 'telecom' types make the modem invisible for the operating

system. This is very interesting when a dumb terminal is connected via modem

because the operating system 'sees' a dumb terminal directly connected (see

Appendix A.5).

In the opposite case, if the modem must be controlled by the operating system

(ex: fax software), set the 'direct' type and use the proper network service

(server telnet with the RFC 2217 extension).

The following parameters depend on the LINE TYPE value.

1 2 ... 19 20 21 22 23 24 25 26 27 28 29 ... 101 102
