?This driver runs on PC's COM hardware with either PPP or SLIP frame, it supports both directly connected line and indirect modem connection.
!RIEM(FRAME)Media Frame Type
?The driver defaults to use SLIP frame type, you can select PPP frame type instead if so required.
@SLIP
PPP
!RIEM(INT)Hardware Interrupt Level
?This parameter specifies the interrupt level of the COM port the driver will operate on. Normally, use 4 for COM1/COM3 or 3 for COM2/COM4.
@4
3
!RIEM(PORT)Serial Base I/O Address
?This Parameter specifies the base I/O address of the COM port the driver will operate on. Normally, use 3F8 for COM1 or 2F8 for COM2.
@3F8
2F8
3E8
2E8
$RIEM(ACCM)PPP Asynchronous Control Character Map
?This Parameter provides a way to negotiate the use of control character mapping. The field is four octets where each numbered bit (31-0) corresponds to the control character of the same value. Set the bit to 1 to map. Normally, set it to zero.
0
FFFFFFFF
!RIEM(ACCOMP)PPP Address, Control field Compression
?This parameter provides a way to negotiate the compression of the data link layer address and control fields. By specifing YES, the peer is informed that the implementation can receive compressed Address and Control fields.
@YES
NO
!RIEM(PCOMP)PPP Protocol field Compression
?This parameter provides a way to negotiate the compression of the data link layer protocol field. By specifing YES, the peer is informed that the implementation can receive compressed protocol field.
@YES
NO
$OIEM(MAGIC)PPP Magic Number
?This parameter provides a way to detect looped-back links and other data link anomalies. The number entered will be used as a seed to generate an unique magic number to be used locally.
1
FFFFFFFF
$OIEM(MRU)Maximum Receive Unit
?This parameter may be sent to inform the peer that the implementation can receive larger frames, or to request that the peer send smaller frames when PPP frame is used. If not specified, the default is 1006 for SLIP and 1500 for PPP.
76
1500
$OIEM(IPADDR)PPP Local IP Address
?This parameter provides a way to negotiate the IP address to be used on the local end of the PPP link. If specified as zero or not specified and the peer is capable of assigning IP address, local IP address will be assigned through negotiation.
0
FFFFFFFF
!RIEM(TCPIPCOMP)TCPIP Header Compression
?This parameter is used to indicate the ability to receive compressed packets using Van Jacobson algorithm. VJ compression reduces the size of the TCP/IP headers from 40 bytes to as low as 3 bytes. This could cause significant throughput improvement.
@VJ
NO
!RIEM(OPEN)PPP Negotiation Mode
?This parameter indicates whether the PPP configuration negotiation on the local end is active (initiate request) or passive (listen to request).
@ACTIVE
PASSIVE
!RIEM(BAUD)BAUD rate
?This parameter specifies the line speed of the serial link. 2400 baud used if not specified.
300
1200
@ 2400
9600
19200
38400
!RIEM(DIRECT)Link Connection Type
?This parameter specifies the type of the serial line connection, whether it is directly connected line or indirectly connected (modem connection) line.
@YES
NO
$OIEM(DIAL)Phone Number to Dial
?This parameter specifies the telephone number to dial automatically when the driver gets loaded. Applies only when the link connection type is NOT DIRECT.
0
FFFFFFFF
$OIEM(LISTEN)Listen and Answer the Phone
?This parameter instructs the driver to put the modem in answer mode when the driver gets loaded. Applies only when the link connection type is NOT DIRECT.
