Wanting a way to test the serial port I recalled minicom and after
getting it set up on /dev/ttyS0 it seems happy with Com 1. The old
/dev/modem is gone on F7. But now what is a way to drive the serial port
pins to a constant plus voltage with minicom?
In minicom it can help {and if only using a 3 wire cable be required} to
disable the setting where it looks for HW handshaking from the remote
device:
| A - Serial Device : /dev/ttyS1
| B - Lockfile Location : /var/lock
| E - Bps/Par/Bits : 9600 8N1
| F - Hardware Flow Control : No
| G - Software Flow Control : No
If you are using a cable with more than 3 wires, you might need to check
that the DTR, DSR lines a wired up appropriately - ie that the remote
device is not incorrectly telling your computer that it is not ready.
A simple trick is to connect pins 2 and 3 {transmit and receive}
directly on your serial port, and see if you get characters typed echoed
back ?
