pppd[0] died: Serial port open failed (exit code 7)

I am using a verizon usb cell modem and qinternet to connect to the internet. Periodically I get disconnected with the following error:

Status is: disconnected
pppd[0] died: pppd options error (exit code 2)

When I try to reconnect the following error displays:

pppd[0]: Failed to open /dev/ttyACM0: Input/output error
Status is: disconnected
pppd[0] died: Serial port open failed (exit code 7)

The only way to reconnect is to reboot. Is there a way to “repair” the serial port connection without rebooting?

thanks

man pppd:

2 An error was detected in processing the options given, such
as two mutually exclusive options being used.

7 The serial port could not be opened.

Try unplug/replug.
