Appendix B. MIP Mode Using the DOS Device Driver 13

APPENDIX B. MIP MODE USING THE DOS DRIVER

LDVSLTA.SYS is the driver used for non-

LNS applications running on a DOS

or Windows 9x platform involving the SLM SiteLync network modem in MIP

mode. This driver will not function on Windows NT. If the MIP mode

driver

installation was performed as described in STEP 1 of the “S

ETUP AND

OPERATION

” section, the MIP mode driver (ldvslta.sys) was loaded onto the host

PC. In addition, a device driver was added to config.sys similar to the following:

device=c:\progra~1\ctipro~1\slm\ldvslta.sys /B57600 /P1

/D1

Figure 8 shows the host PC configuration when MIP mode is used.

The SLM SiteLync in MIP mode can be connected to the PC either locally via an

switches as follows, depending on the choice of local or remote connection:

SLM Model Local / Remote Switch Setting

SLM/AY Local OPTION 2 : UP

All Others Local RUN/CFG : CFG

tch settings, be sure to power cycle or RESET the

SLM SiteLync.
