Thirded on screen.

But if you do a lot of binary xfer, the hw flow control may be worth a bit more patience.
And you can then use Ctrl_S (xoff**) and Ctrl_Q a bit more freely (e.g: scrollstop -vs- /usr/bin/less; since you're only extruding at 9600), and yer scroll 
states won't get obfuskomacated.

Check BIOS/CMOS settings on both machines, for mbrd's integrated UART/ComN (toggles).
Old IBM defaults for primary&secondary were irq4:3F8 and irq3:3E8

Check PSU for negative12v on psuPin12 (usu.blue) -vs- adjacent psuPin13 (black:grnd)

In rs232 terms, the DSR+[D]CD (usu.combined) & CTS signals minicom wants to see asserted from the OtherEnd, ain't.

Since MrCyan's prolly a NullMdm/CrossoverCable, ThisEnd's handshakes*** are actually coming from OtherEnd's DTR or RTS pins, resp.
You may think MrCyan is weird, but that MrMagenta is a downright reservoir dog.

Curious my ageing brain still responds to AT&F, but I can't juggle this newfangled capex or optex without fumbling the PON

*** speaking of language, would the modern vernacular now be 'Data Daps' ?

In which case, then let us lower our respective altitudes and engage in pheremonally fragrant activities on the dancefloor
(transl: 'Get down, get funky.')
