8-16 Troubleshooting Guide

To program the modem, set the CSMIM2 port to “slave”. The following example shows the code to use assuming the port

is 16.

port 16

set port mode slave

reset 16

quit

Try to Telnet to the port.

The following is an example of how to do it:

If the CSMIM2 address is 134.144.35.60 and the printer is on port 16, your port command would be:

telnet 134.141.35.60 5016

The following response may vary depending on your system software:

trying

Program the modem. Depending on the modem used, the commands to program the modem parameters may be different.

Table 8-2 lists the modem parameters and the associated commands according to two of the more widely used modems,

Hayes AT and US Robotics. For programming information of other modems, refer to the associated documentation.

Write the commands to the modem NVRAM. This is usually done using the AT&W command. (Refer to your modem

documentation for further instructions.)

Stop the Telnet session by pressing CTRL -]

In the Admin Mode, set the port back to CLI Mode.

Example:
