The following two tables are the standard connection specifications used by
ICD for our standard printer and MODEM cables. These should work for the most common printers and MODEMs or they may need to be modified according to the
special needs of your particular installation.

The following table is used with a Toshiba P321 printer with serial interface and is only shown as a guide. All handshaking lines are connected even though
most applications would work with only XMT, RCV, and GND. The Toshiba printer is a DTE device and the MIO is also a DTE device. This requires the crossing
of XMT and RCV. Be sure to check your printer manual for pin out as most printer connectors will vary. If your serial printer is a DCE device
(not DTE) then XMT would connect to XMT and RCV to RCV.

Null MODEM Cable Connections
This will allow transfer of files between an MIO serial port or P:R: Connection and an IBM PC or Atari ST without using MODEMs. Tie pins 6 and 8
together at the DB25 end (PC or ST).
