ABSTRACT:  TEST.C                                                            


SDLC\HDLC Note:

TEST.C is a simple example program for the SeaMAC DOS driver. The hardware 
configuration for the program is determined by the setup file.

Cables:

For SDLC\HDLC mode, transmit, receive, Tx Clock, and Rx Clock are needed. The
program may be used in a stand alone loop-back configuration, or with another
PC with an ACB or SDLC adapter installed. For most ACB adapters use TSET or
TT for an output clock and RxC as an input clock. Please note that TSET
(Transmit Signal Element Timing) is the EIA-530 equivalent of TT, the RS-232
signal Terminal Timing. For a loop-back plug connect the Transmit signal(s)
to the receive signal(s) and the TSET (EIA-530) or TT (RS-232) signal(s) to
the RxC signal(s).

  For Loop-Back Plug:

     For Single Ended (RS-232, MIL-188/114)
	Connect Tx to Rx
	Connect TSET or TT to RxC

     For Differential Interface (RS-530, V.35, MIL-188/C, etc.)
	Connect Tx+ to  Rx+
	Connect Tx- to  Rx-
	Connect TSET+ or TT+ to RxC+
	Connect TSET- or TT- to RxC-

  Point to Point Cable:

     For Single Ended (RS-232, MIL-188/114)
	Connect Tx at point A to Rx at point B
	Connect TSET or TT at point A to RxC at point B
	Connect Tx at point B to Rx at point A
	Connect TSET or TT at point B to RxC at point A

     For Differential Interface (RS-530, V.35, MIL-188/C, etc.)
	Connect Tx+ at point A to Rx+ at point B
	Connect Tx- at point A to Rx- at point B
	Connect TSET+ or TT+ at point A to RxC+ at point B
	Connect TSET- or TT- at point A to RxC- at point B
	Connect Tx+ at point B to Rx+ at point A
	Connect Tx- at point B to Rx- at point A
	Connect TSET+ or TT+ at point B to RxC+ at point A
	Connect TSET- or TT- at point B to RxC- at point A
