Parameters

/n:names

Defines the naming convention to be use for the DigiCHANNEL ports. names consists of an optional stem followed by the starting device number. The new stem must be enclosed in double-quotes (""). If the stem is omitted, COM will be used. If the number is omitted, 3 will be assumed. If the /n parameter is not specified, the default name COM3 will be assigned to the first port. 

/n:"digi"0 	DIGI0, DIGI1, DIGI2, ... DIGIn 
/n:4		COM4, COM5, COM6, ... COMn 
/n:"qdev"	QDEV3, QDEV4, QDEV5, ... QDEVn

/b:baud

Sets the default baud rate to be used for all ports. If this parameter is not specified, all ports will be set to the OS/2 default of 1200 baud. Baud rates of up to 38,400 are supported. Use the DMODE.EXE command to set baud rates of individual ports. 

/b:9600	Initializes all ports to 9600 baud.

/d:dtype

Sets the initial data type (parity, character length and number of stop bits). If this parameter is omitted, the OS/2 default data type of even parity, 7 data bits and 1 stop bit is used. The syntax is [pds], where p is E, O or N; d is 8, 7, 6 or 5; and s is 1 or 2. All three values must be supplied, in the correct order. 

/d:N81		No parity, 8 data bits, 1 stop bit.

/f:digipath

Defines an alternative directory path for the driver and data files. If this option is present, all files from the distribution diskette must be present in this directory. 

/f:d:\drvr\digi	All data files are in D:\DRVR\DIGI.

/v:messagefile

Forces the driver to direct all verbose messages to the file named. If /v: is given without a filename, messages will be placed in \XALL.MSG. This flag prevents any information from being displayed on the console; useful in some situations, as when the machine is a headless server, where calls to Standard Output will cause problems. Without this flag, all messages will appear on the system console. The message file is overwritten each time the system is started.

/v:errmsg

Writes banner and other info to file \ERRMSG. 

/v:	Writes banner and other info to file \XALL.MSG.

/a:a

Enable the alternate pin assignment of Data Carrier Detect (DCD) for all ports (see discussion of Alt-Pin processing.

Per-Card Parameters The remaining three parameters are per-card parameters, and are used to inform the driver of the type of board and where it is to be addressed in the hosts I/O and memory buses. These parameters are mandatory, and must be given for each board! The per-card parameters must be given in complete sets, and the sets must be separated by commas.

/t:card

Defines the card type to the driver. Legal values for card are:

  • i for the ISA C/X,
  • e for the EISA C/X,
  • m for the MC C/X,
  • p for Xem (PC/Xem, MC/Xem or EISA/Xem)
  • x for COM/Xi boards.

This parameter must be omitted for PC/Xe, PC/Xi and MC/Xi boards. The designators i, e, and m must be followed by an additional two digits defining the number and arrangement of DigiCHANNEL C/CON-16 or C/CON-16e concentrators on each host adapter channel.

If the concentrator(s) are connected to the host adapter via a dial-up or leased line (remote concentrators), each of the two digits must be followed by a parameter, enclosed in parentheses, specifying the synchronous communications mode to be used for that line. See the Appendix for a list of available synchronous communications modes.

/t:i10 ISA C/X, one local concentrator on line 1 only.
/t:e11 EISA C/X, one local concentrator on each of lines 1 and 2.
/t:m21 MC C/X, two local concentrators on line 1 and 1 on line 2.
/t:e12 EISA C/X, one local concentrator on line 1, and two on line 2.
/t:i22 ISA C/X, two local concentrators on each of lines 1 and 2.
/t:i2(21)3(27) ISA C/X, two remote concentrators on line 1, and two remote concentrators on line 2. The concentrators on line 1 will use mode #21 (76,800 baud, 8-wire, external clock) to communicate with the host adapter, and the concentrators on line 2 will use mode #27 (614,400 baud, 8-wire, internal clock).
/t:x COM/Xi (4 or 8 channels)
/t:p PC/Xem, MC/Xem or EISA Xem

/p:port

Defines the I/O port address for the card.

/p:300 Board is addressed at I/O port 300h.
/p:2005 EISA board (EISA C/X or EISA/Xem host adapter) is in slot 2 (EISA I/O addresses are 4 digits : the slot number, followed by 005). When plugging an ISA board (PC/Xe, ISA C/X host adapter, etc.) into an EISA machine, the /p parameter must contain the 3-digit I/O address as set by the DIP switches on the board, and not the 4-digit address based on the EISA slot number.

/m:mem

Dual-ported memory starting address. This is the full 32-bit hexadecimal address of the beginning of the board's dual-ported memory.

/m:d0000 Sets dual-ported memory start address to 0D0000h (in the BIOS expansion area between 640K and 1 megabyte).
/m:e80000 Sets start address of E80000h (in the fifteenth megabyte). EISA and ISA boards (except the COM/Xi), may all share the same memory starting address. COM/Xi and all Micro Channel boards must each have unique memory addresses.

Examples

The following examples start out with just the minimum to install a DigiCHANNEL board. After locating an example for your type of board, read the rest of the examples for optional situations that may be appropriate to your application. Default options will be altered by your application program(s) when you configure the application.
