The first line specifies a mapping to some TCP/IP host port ("10000" in this example), while the second line connects this mapping (TTA0) to the on-board serial line controller having the name "COM2" in CHARON environment.
Refer to this section for details of the mapping.

Console Parameters
CHARON-AXP console lines have some specific parameters:
| Parameter | Type | Value |
|---|
rts[<line>] | Text string | "On" - assert the RTS (Request To Send) signal "Off" - clear the RTS signal (default) "DTR" - assert the RTS signal as soon as the DTR signal is asserted
|
dsr[<line>] | Text string | "On" - always reports DSR signal assertion "Off" - always reports DSR signal deassertion "DSR" - use the DSR signal of the physical serial line (if configured) "CD", "DCD", "RLSD" - use the CD (carrier detect) signal of the physical serial line (if configured)
infoThis parameter is applicable only for line "2" of QUART. | |
communication [<line>] | Text string | "ASCII" - for connection to terminals (default) "BINARY" - for serial lines carrying binary (packet) protocols, which are used mainly for communicating with PLCs
|
line[<line>] | Identifier | This parameter is used to connect a particular serial line mapping interface to the controller. See below for details. |
| Info |
|---|
Note that the "line" parameter in the table above in the case of QUART. to the additional on-board serial line controller "COM2" Example: |
All the values in this table are case insensitive.
Example:
set QUART OPA0 rts[2]="DTR"
set QUART OPA0 dsr[2]="On"
set QUART OPA0 communication[2]="binary"
|
| Warning |
|---|
Line 2 of the QUART is the only one which can be used for connecting modems. Therefore, the "DSR" parameter for that line (i.e. "dsr[2]") is internally set to the appropriate value (CD") but can be changed from the configuration file. Values for the "rts" and "dsr" parameters for the lines other than 2 are not visible for any applications running on CHARON-AXP. Back to Table of Contents
