Modem Connections
Dial Up Modems
&E6 means Xon/Xoff not passed through
&E8 means Enq/Ack pacing off
&E10 means Normal Mode flow control off
&E13 means Pacing on
&E15 means data compression enabled
$MB9600 selects 9600 bps on-line
$SB9600 selects 9600 bps at serial port
$BA0 means Baud Adjust is off, speed conversion is on
&W1 causes modem to store its current parameters into non-volatile
RAM, and modem will load these for future sessions instead of reading
factory ROM and DIP switch defaults
Enabling Hardware Flow Control
The following example shows a common method for setting hardware
flow control in HP-UX 10.x series 700 and 800 machines. However,
remember that HP technical support is the best resource for information
about setting up hardware flow control.
The example is presented in two phases:
1. Adding devices with the SAM interface.
2. Setting bits in the minor device number to enable hardware flow
control.
In this example an outbound device (/dev/cul0p1) and an inbound
device (/dev/tty0p1) are added without hardware flow control. Next,
the new devices are renamed and the mknod command is used to set
hardware flow control for the devices.
To use this example to set up hardware flow control on your own system,
substitute your device names where appropriate. Additional information
may be obtained from termio(7).
Adding the devices
1. Use SAM to add the modem devices.
Choose "Peripheral Devices," then "Terminals and Modems."
2. Write down the names of the devices you create.
