===Serial cable===
===Serial Cable===
The ideal cable to go from a PC to a Model 100, 102, 200, or 600, is "9F/25M serial null-modem full-handshake".
[[Model_T_Serial_Cable]]


That's an uncommon configuration to find pre-molded in a single cable, but one way to find them is to search for "HP Plotter Cable" or "Serial Printer Cable".
===Parallel able===
[[Model_T_Parallel_Cable]]


The serial port on a Model 100 is wired DTE, the same as a com port on a PC, but with a female connector, unlike any pc.
===Barcode Wand===
[[BCR_PORT]]


This is a backwards configuration from everything else today. There is some suggestion that maybe this is actually the original standard, and IBM came along later and changed it by putting male connectors on their PCs, but in any event, DTE ports being male has been the universal standard now for decades.
===RAM Expansion===
*Any modem or printer or digital scale or any other kind of peripheral with a serial connection will be wired DCE with a female connector, usually 25 pin.
[[PG Designs M100 RAM Expansion|PG Designs]]
*Any serial port card or usb serial adapter for a PC will be wired DTE with a male connector, usually 9 pin.
 
That means that usually you always need some kind of adapter between a PC and a M100.
 
The easiest cable to assemble from common parts you may already have lying around, is a common 9F/25M serial [https://www.cablewholesale.com/products/serial-modem-cable/at-modem-cables/product-10d1-02303.php modem cable], combined with a 9F/9M [https://www.monoprice.com/product?p_id=1203 null-modem adapter].


Ideal, all-in-one cables:

Slightly less ideal cables. All-in-one, but not full-handshaking:
===Option ROM===
*[https://www.monoprice.com/product?p_id=479 Monoprice 479]
[[Model 100 Option ROM pinout|Pinout]]<br>
:Shorts RTS/CTS to self-satisfy on both ends.
:Works fine for TPDD client/server connection, and almost everything else, since there isn't even any way to *set* hardware flow control in either BASIC or TELCOM anyway.
:But the hardware in the M100 *can* actually do rts/cts, if you manipulate the UART registers yourself from a machine language program. The only software I know of that does this is HTERM. So this cable is NOT suitable for HTERM.
